its done by AT*, as different teams play different # of matches you have to take an average.

so lets say for the red alliance

r1c = AT* for red1

r1c/(r1c + r2c + r3c) = r1%c to match n
r1%c * redScore = r1mc (red1's match contribution)

also a teams AT* is calculated on a per event basis. So if you go to a second regional your teams match contribution is based on your performance at that regional

However your ETC is the average ETQMC over all matches at all regionals

There is no way to have a negative as points against are not factored. that being said, Just as I can calculate MC and RC I am about one days worth of coding away from a DC (defensive contribution). My hope was to present a madden-like scale for each team. So before a match you could plug in the 6 teams and see what you are in for (based on the #s rather than based on teams claims)

also I wanted to add an alliance selection app, that estimates a teams contribution to your alliance. For example if you have 2 minibots better than the 3rd then their MC would be dropped from their value. I think this would come in handy in picking out teams your may over look for your 2nd pick. Obviously you would want to check it against your scouting sheets...

Did you run the numbers for San Diego?

Unfortunately SD was one of the two regionals that didn't post to the twitter feed. Supporting SD and Lake Superior would force me to parse the first site, and break the algorithms I plan on implementing later. Unfortunately when it came down to priorities, I have selected to abandon non tweeted events for now.

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!

[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...

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.

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.
