Re: What happened in Curie???

I'm not going to go in the ranking of the robots picked. I would rant on for a whole page on how bad half the decisions were...

Besides the quality of the robots, if anyone else noticed, only 6 of the robots were 4 digit number teams. 18 teams were either double or triple digits. No rookies were picked, 2 2000 teams were picked, and 4 1000 teams were picked. It seemed that the captains didn't even look at younger teams. Experience is no excuse. Some of young teams that were not picked won regionals, or made it to the finals at their regional. These teams obviously know what it takes to win something, and have just as much experience in this game as a lot of veteran teams. And not mention, older teams are replaced every 4 years. Mentors are the only thing to remain a constant in any team, for the most part. A lot of the young teams that made it to championships have mentors that have been on teams before. In this sense, these teams have the same experience as veterans.

I'm disappointed in what Curie turned into. I would hope that it will change for next year, but I doubt it will change at all.

Having what it takes to win at a regional does not translate into having what it takes to win at the Championship. Sorry, but them's the facts. Think back to last year's NFL playoffs. The Baltimore Ravens had a young team that had what it took to get into the lower-level playoffs. Then they met up with a team that had what it took to get to the Super Bowl. When a bunch of teams that have what it takes to get to the regional finals come up against a bunch of teams that have what it takes to get to the divisional finals (where there are twice as many teams in the division), the teams that have what it takes to get into the divisional finals will win out, every time.

What rookie teams would you suggest should have been picked? As far as I am concerned, the alliance selection seemed very well done. Obviously there were a couple teams left that I thought could have been strong second picks, but overall I was very happy with all of the alliances. If a captain is picking there alliance based off of rankings alone, they will lose. Especially at the championship when you only play 7 matches, your ranking will be very driven by your alliance pairings in qualifications. I know we were ranked 36, but were top 3 or 4 in opr and that was even with 2 matches we had in which one robot either did not show up or was disabled the entire match, thus drawing constant defense from 2 robots in those matches.

Scouting is what wins regionals and championships, and all of the truly top teams have not achieved the success they have without very careful statistical scouting of every team. Although our alliance ended up losing in the quarterfinals, and we definitely had our chances to win the matches, I feel that the winning alliance out of Curie was incredibly strong and I was proud to have them representing our division.

I do completely agree that something needs to be changed about the game and how a purely defensive robot or even worse a no show team can end up as an alliance captain. Of course if there is a robot so incredibly awesome at defense then they should seed very high but the idea of a team that is not particularly good at anything can seed in the top 8 is wrong. This year, 247 was one of those teams that were just so incredibly good at pinning other robots that you just had to be impressed and I thought that that was an incredible pick for the 217/68 alliance, as 68 definitely was able to score more with another robot setting pins for them.
There also needs to be some type of filler line or something for no show teams, as particularly this year, having a non functioning robot or a no show was essentially a death sentence. Perhaps what needs to be done is to cut down the number of teams at the Championship event. I feel that too many teams have the opportunity to buy in without actually demonstrating that they can win. With less teams at the event, FIRST could increase the number of qualification matches resulting in less of an influence from luck. Maybe instead of so many teams buying in, FIRST should add an award at regionals for the highest scoring or best performing robot.

Obviously these ideas are not completely refined, but I think there is a serious flaw in the system when teams that do not run for multiple matches are becoming alliance captains, and there are still no shows at the championship event.

As with any sport, the championship should be the absolute best teams competing. I dont think we really saw truly exciting matches until the elimination matches at the championship.

Re: What happened in Curie???

I thought Curie had the most "normal" alliance selection of any of the divisions. Let me share some things I observed.

First, our team agrees that 7 matches is really not eough to statistically determine who the top 8 really is. Unfortunately, teams that are clearly not top 8 caliber will get into the top 8. This is one of the reasons the FIRST in Michigan district model had 12 matches at each of the district events.

In our team's opinion, there were 4 teams in the top 8 that were not really top 8 caliber. Such is life at the Championship.

Our team scouts every match and takes the best statistical data we can for each and every team. Scouting the actual matches is the best way to definitely determine if a team will make a good partner in the elimination rounds. On Friday, we have a 3 to 4 hour strategy meeting where we make a pick list of the top 24 teams based on our scouting data and feedback from the drive team. We use feedback from the drive team to help determine if a team is hard or easy to work with. Our scouting team then focuses on the teams that are very close in performance on Friday to see how they are doing on Saturday morning matches. We really focus on teams that are performing better as the weekend moves along.

OPR and other indicators are really only needed when you can't actually watch the matches in person. We do not use OPR because OPR will not get you to Einstein. Period.

Here are some other things we do not use:

- Record in the division
- Ranking in the division
- Performance at Regional events
- Team number
- Where a team is from

I can't even tell you what 68 or 247 records or rankings were because we didn't care.

For the last 5 years, I have witnessed the strangest picks by teams in the top 8. Teams that would have been our 4th or 5th pick slipped all the way to the bottom of the draft. This year in Curie was the first time that I can remember that the teams selecting partners during the draft basically picked how we would have picked (except 68 as they should not have been around for us). With 87 teams in the division some good teams will be overlooked and there is no way aroud it.

I want to make one more point. The serpentine draft has caused a lot more teams to decline. I can tell you that our team prefers not to decline, but will if we feel that it gives us a strategic advantage. We declined 1806 (the #2 seed) not becasue we didn't think they were a good team (they were very high on our list), but simply because of the serpentine. If the serpentine did not exist, then we would have definitely accepted their invitation. Team 1806 knew prior to alliance selections that we were going to decline as I told their team that we would decline. They used a very good strategy picking us anyway so no one else could select us. They basically forced 217 and 399 to form their own alliances (they asked 399 to be their partner too and 399 declined).

Our division had only 14 teams with a positive "plus/minus". Plus/minus (for our team) is the number of points scored by the robot minus the number of points in the robot's trailer. This year it is the biggest indicator of a team's contribution. Obviously, for pure defensive bots we only look at points scored in their trailer as +/- will, by definition, always be negative. As the #7 seed, we knew we could get two very good robots to complement our playing style. We felt we could build a better alliance from #7 than from #2. And for those of you wondering, I didn't realize we had an all Michigan alliance until about 10 minutes after selection. It is just the way things worked out.

Someone made a comment about high number teams not getting picked. We had a few high number teams on our list (I was suprised no one picked 3115), but we had the #7 and #10 picks in the draft.

Re: What happened in Curie???

That is a great post and I will probably be saving it to help us with scouting in the future. I too could not believe that 68 was till around for you guys. On my list I had them at least in the top 5 including your team.

One other rookie team that I was slightly suprised not to see selected was 2815, but given the teams that were picked I dont see what team they could have been selected in place of. Overall I thought the selections went very well and all of the matches were fairly close as a result.

I am still disappointed that we did not have the opportunity to play with 188, 217, or 68 at all at the championship, but that is just the way the matches go. There is always next year to get the chance to play with these incredible teams.

Yo guys, were really great at Atlanta as well, you guys had an amazing alliance, and put up a great and enjoyable show. We would like to work with you guys as well in the future. Like you said, there is always next year!

Re: What happened in Curie???

I have to just chip in a couple points about the earlier discussion involving defense.

I don't like overly defensive games, they tend to be boring, but defense has a definite role in FIRST, in my opinion. It's a very very large part of what separates FRC from just being an "engineering competition," "race," or "skills contest."

Secondly, where do you draw the line between "defense" and "strategy?" Is pinning a robot to aid your alliance partner's scoring effort defense? Is reserving your balls until the end of the match to ensure the other team doesn't get additional ammo defense? Is swerving your trailer out of the way of your opponent's best scoring machine defense?


As for rankings, the only real solution is to play more matches. How you accomplish that has been debated and contemplated for years, but no clear solution has emerged.

I have to agree with Paul's comments here and say that on our end our team also does a fair amount of scouting. We usually have a 3 hour meeting on Friday with our scouting team and also list the top 20 robots that we should pick. Once we get the input from the scouting team, the drive team talks over the picks made by the scouting team and we order them based on information given to us by the team.

During this event we also collaborated with team 188 and greatly benefited from their data. One of the major data points that our driver Brad wanted to look at was the amount of balls in the robot's trailers. This influenced our picks to a point, but we stuck primarily with the information from our team members.

As for the decline, we also mirror Paul's thoughts on this. Although we would normally accept the invitation to join 1806 on the playing field it was a matter of strategy, alliance picking, and bracket positioning that caused the decline. We felt that we could create a better alliance being the fourth alliance. We knew that 217 would not be available by the time that it was our turn for the pick and it was an excellent move by 1806 to breakup the possibility for anyone else to build up an alliance with them. We felt we had a strong chance with 188 and 329 to take it to the finals and we nearly had it, taking the showdown to 3 matches We were very happy with our alliance and the effort we made for Einstein.

Paul Copioli from 217 Thunder Chickens.....

THANKS for your post and explaination of how your Team scouted for the selection of the elimination rounds.

As a mentor for 1983 SKUNKWORKS I would be curious to understand where our Team stood in your findings or other Teams findings, and as a whole where you saw our Teams weaknesses.

THANKS!

Re: What happened in Curie???

Thats how it goes, 2 points Saturday morning we would have seeded 3rd, instead we seeded 10th. As a rookie team we knew that it was going to be difficult to be selected as a second round team, and having a communication error in our last match on Friday hurt our stats for Friday night. Without that match where we were dead it put us right in with the teams selected in the second round, but we know that with the quality of teams in the hunt as second picks it was going to be tough to get picked.

We were praying that two teams would pick within the top 8 so that we could move up into the 8th seed, and I can tell you we put quite an effort into scouting and would have made a tough 8th alliance. But i've been around long enough to know that this alliance selection went as normally as it could have, and if teams picked and declined properly we shouldn't have moved up. So if anything I applaud the teams in the top 8 for making some solid alliances.

I would have to agree with Paul. The ONLY fair way to make the ranking system more reliable is to complete more matches.

Paul,

Thanks for explaining your scouting and selection philosophy and posting your scouting data and selection list on the other post. It helps us understand how good teams select their partners.

I must say that I am very surprised you do not take into account how many moon rocks the human players attempted and scored. According to Team 188's scouting database, your human player do not attempt to score very often because your strategy is to have the human player feeds moon rocks into your robot. However we can not say that for other teams. Using your data in the raw data sheet, if you sum column F which is Moon rock scored by robots in all the matches you get 2354. And if you sum column J which is Moon rock in trailer you get 5080. This shows that only 46% of the moon rocks are scored by robots.

If we look at Team 188's database, the human player percentage ranges from 21% to 77% with a mean of about 47 and standard deviation of about 10. Since human players scored 54% of the moon rocks, picking a team that has a 60% shooter rather than a 30% shooter in a 100 point game would mean a difference of 16 points, which is quite significant. In past years the role of human player to scoring is limited. I don't know what percentage the human player should contribute to the score in an ideal game. I feel that this year their contribution to the final score is on the high side and thus scouting data should not ignore them. Another observation I have is robots can be defended but you can not defend against a good human player. They just keep putting moon rocks into trailers.

Re: What happened in Curie???

Wouldn't defending against a good human player simply be moving my robot to the side of the field that they weren't able to reach, if that was my concern?

I would be more afraid of a highly mobile, highly effective robot like 217 unleashing a stream of moon rocks anywhere on the field into my trailer than I would be of a good human player taking a low percentage shot halfway across it.

Re: What happened in Curie???

Ed,

You make a good point, but for our team and our strategy we intended to starve the field of rocks. When a human player was on our alliance, the first thing they were told was to not shoot the moon rocks unless the trailer was stopped generally in front of them.

We prioritized on a high capacity dumper that could human load from the top and could human load in auton. Combined with our human loading in auton, we could keep many of our balls off of the floor and "starve" the field. In essence, almost every ball we were pciking up from the floor was not ours.

There were many ways to wn this year, but this strategy worked for us.

Re: What happened in Curie???

I think that you will notice that the Championship winning alliance used this same strategy. It was also used very succesfully in the Michigan Championship eliminations.
