The FIRST Alliance - A whole new way to play

[Siri]

I like the overall OPR and DPR. Any chance of including rankings or doing it by event as well? And/or by auton, teleop, end game (Twitter-dependent)? Other cool OPRnet like features would be great, too--sched, or even selected matches. (OPRnet is fantastic, but I tend to do better with GUIs...)
Ok, I like OPR. Flawed as it is.


Also, any thought in including the team's standings & awards on each event page and/or an overall team page?

In elimination mode for an event, is there any particular reason that the teams listed in "Elimination Teams" are not hyperlinked?

Could you also include a paper explaining how you're calculating OPR and DPR? And on that note, could you include separate columns doing OPR by hoops/bridge?

It's still great though

It isn't in the roadmap yet, but we're working on it now actually.

OPR and DPR are calculated as described below. This is the same way that they are calculated for OPRNet and all other opr programs.

Take all teams at an event, count this set as T.
Create a matrix which is TxT, so you end up with a column and row for every team. We will refer to this as M and will describe how many times a team plays another.
So if T was (1,5,9) the M would be
1 5 9
1 - - -
5 - - -
9 - - -
Also, make a matrix that is 1xT and this will be O and will contain sum of all points a team scored
and thirdly, made a matrix 1xT which will be called D, and will contain sum of all points scored against a team
Now, for every match at an event follow the next few steps of logic
1) Increment M[A,B], if A!=B, increment M[B,A]
2) do 1 with A = red 1, B = red 1
3) do 1 with A = red 1, B = red 2
4) do 1 with A = red 1, B = red 3
5) do 1 with A = red 2, B = red 2
6) do 1 with A = red 2, B = red 3
7) do 1 with A = red 3, B = red 3
8) 2-7 with blue instead of red
9) for all red teams, O[red 1-3] += red_score
10) for all red teams, D[red 1-3] += blue_score
11) for all blue teams, O[blue 1-3] += blue_score
12) for all blue teams, D[blue 1-3] += red_score

then take inv(M) * O, and you get OPR's
and take inv(M) * D, and you get DPR's

this write-up may be a bit flawed, but thats the general flow of how OPR's and DPR's are calculated.

Also, right now we do have OPR's and DPR's per-team per-event, but as of now, we don't really have a clean place to put those details. So the power-rankings page is just the highest average OPR/DPR.

Yes.....a VERY good reason......I forgot, its fixed now, thanks for the bug report.

Glitch in eliminations view: The X's cascade back. For example, the second alliance won the regional in the finals vs the first. The first alliance is listed as losing all previous matches in the diagram.

I really like where this website is going. While you're doing OPR, as someone above mentioned, Teleop OPR and Bridge OPR are really the only useful ones this year. While you're at it, CCWM is another measure of team performance.

I've never heard of CCWM, I'll look into it a bit.
Second, the way the X's work is showing how a team is eliminated, so instead of showing where they won up to and crossing them out there, it crosses them out over the whole thing as soon as they no longer make it to the next level. I was probably thinking of doing it more like the former, but probably just use green for all 'won' sections, then red where they were eliminated.

If I recall correctly, CCWM = OPR - DPR. Calculated Contribution to Winning Margin (predictably) uses the team's alliances' winning margins rather than points score by (OPR) or on (DPR) them.

As far as how you're calculating OPR & DPR, this is actually a more loaded question than most years. I don't know if it's what slijin meant, but people are indeed calculating it differently this year, mostly by weighting Co-Op as bridge points. The conversations happened in a few of the different OPR threads, but the general gist was 5 or 10 points per CP.

Looking at the eliminations page, what is the W-L-T column meant to represent? In its current implementation, it appears to be whether the blue alliance won, lost, or tied, but I guess I fail to see how this data is relevant.

After seeing the robot picture feature, what if The FIRST alliance had a robot reveal video feature too? I know that people are asking for matches, but I think a reveal would be interesting and different.

Just an idea.

I second that. There needs to be a place on the internet where all of the unveil videos are kept together, and it may as well be the FIRST Alliance.

[GGCO]

Hmm... really interesting idea. We'll look into it.

I really like this idea, we should have something up in the next day or two.

Okay, that went a little quicker than expected. You can now link any youtube video on TFA.

I was wondering if the videos, or photos that are posted are moderated and how it would be possible to remove either a picture or video? And if this isnt possible if it would be able to make some moderators or allow users to remove team photos
