Great job with your video player though, I enjoyed watching the videos.

Our pleasure! BTW, how are you going to differentiate which team scored which place with minibot...is there a data source for that somewhere without watching each match and hoping the camera catches all the action?

no but by going through by each team's Average Minibot Score
I can calculate the % of their contribution similar to how i do the total contribution
So the minibot will still be an estimate, but after 10 matches it should be fairly reasonable.

So do you add all those match contributions up and average it again to get your final number? If so, have you thought about another iteration to possibly get better numbers?

Interesting, there are always room for more metrics, particularly if you isolate mini bots and penalties. Also it would be interesting if you totaled up contributions across all regionals. I am not sure OPR would be to solve a sparse matrix like that well.

Just ideas, cool algorithm.

Thanks mike and justin for the edumakation!

Yup its an average of all the contributions. Actually a second iteration is an interesting idea, didn't think of that. But yeah it should definitely get a finer resolution than how I am doing it now. Its just trying to keep the server processing to a minimum (I don't want to kill it) . But I think that a second iteration would definitely be worthwhile.

The ETC actually is totalled over all regionals. So 40s ETC is based on BAE and WPI.

Minibots will be isolated next. Penalties along with defense probably in a week or so.

I'm definitely happy with the results for this week. I still think 217 is being overlooked for PR reasons, one of the few robots you can't find much on. However every set of numbers I run they are at the top of the list.

I think OPR takes into account elims, which reflect more on the alliance rather than the teams, thats why i exclude elims from my calculations. If you look at one of the week 1 feeds for top25 I go through the motions of finding this out.

THANKS AGAIN MIKE AND JUSTIN!!!!
In spite of not not agreeing with me on stealing ubertubes I still love the show.

[Justin Montois]

Thanks everyone who watched this week. It's great to see the enthusiasm for what we're doing and it really makes all the work that goes into doing the show and the website worth it.

Congratulations to 1114, Simbotics for moving up to number one. You guys really deserve it.

If you have any questions or comments please feel free to email us at mikeandjustinitm@gmail.com or PM Mike or I. We monitor it all week and are always looking for topics to talk about on the show, ways to improve and any insight into the teams.

As always, thanks for your participation, we couldn't do it without the FIRST community. Good luck to all teams competing week 3, we'll see you next week!

PS: We apologize for the loss of signal towards the end of the show.

PPS: We failed AGAIN to record it. Third times the charm.....

Thanks everyone.

The expert polls were made public last week.. Any chance of the same this week? Or am I just missing it completely?

They said they will be posting them later...

OPR doesn't use elims for the same reason, It was considered a couple years ago and it just skews without adding value. This is why I like to call the bot with the highest OPR "Qualification Match MVP"

Yeah I've thought about dropping a teams first 2 matches, but the logistics of doing that are a little difficult. I still would like to figure out a way, because many teams don't get the kinks worked out til their 3rd Q match or so.

Both ETC and OPR favor teams that worked from the very 1st Q match, which may not be the best team by the end of the regional

also now that I go match by match, I may be able to include elims into my calculations. Although they seem pretty sound right now.

These stats are not a replacement for actual scouting, just another factor to consider.

Very true. Just by looking at teams from Wisconsin (which my team scouted and I saw nearly every match), it was pretty clear that 2826 was better than 234. 234 was very good, put 2826 was significantly due to their minibot. There is no subsitute for watching actual matches.

Actually after implementing the minibot calculations and what not, I found that all teams will not have a positive robot ranking. (robot is the # of points not scored by the minibot)

a robot can have a negative contribution if a minibot goes up but you get penalties. ie you get 30pts for the minibot, but theres a penalty. your final score is 27 with 30 minibot pts. leaving a -3 contribution to the robots in the match.

Interesting how much 1519 dropped on an off week, a bunch of teams jumped them despite not playing this week. I am interested to see the individual expert poles and to see why 1519 dropped so much compared to other robots who were also off this week. All of their competition from Manchester improved in rankings compared to teams who also played in week 1 (40 played both weeks and moved up a spot, 175 only played week one, they dropped 8 spots but 10 new teams were placed above them so they actually improved compared to the same teams as last week, same for 131.)

[Chris is me]

It's interesting to see what great teams are more easily "forgettable" (1519, 2016) and which are not (148).

I didn't vote this week as I was competing, but if I did, 40 would be in the top 3. They drastically improved from BAE.

177 is also quite underrated... but I always say that.
