Ed, sorry I missed out on this discussion. My internet feed was down all afternoon and evening.

Here's a link to all the match data to date. It includes Practice, Qual, and Elim data for all matches at all week1 & week2 events except Oregon and Traverse City.

There are no macros in the spreadsheet to worry about, and no formulas. Just data. You're pretty adept at Excel so you can convince yourself pretty quickly about the TeleOp hoops and Foul Points question.

Note: I found 9 entries where the scores did not add up correctly. Those may be due to late fouls that were not entered into the Twitter data stream.

Thanks Ether for the data, I will take a look at it later tonight.

I just thought of one other point to consider about which OPR to use for World Ranking.

Since I am including elimination matches, and elimination matches have no coop bridge but you can balance with 3 robots and get 40 points. Giving 10 points to balance coop bridge during qualifying rounds is a good idea. Perhaps we should not include elimination round this year since the potential number of points are different.

Just some more things to think about.

I still think you should consider the elims because teams play to the co-op for quals but play to the hoops in elims so it will show who is truly the best.

Ether,

Thanks for the data. The twitter data is worse than you thought. It is not just the Oregon and Traverse City data missing. If you look at individual events, you would find that it is missing a lot of matches (e.g. FL match 105, GG match 1-8, KC match 42-61). This is not your fault but I don't think we can use this data at all. However I did confirm that the teleop points FIRST reported in standings page include the foul points.

YIKES! Nice catch. I had not gotten around yet to examining it for random missing matches. Now that I have, it's even worse than that. I counted 207 missing Qual and Elim matches.

This is not your fault but I don't think we can use this data at all.

I agree: for OPR it is worthless. It still has some use for locating stats like highest scores etc but due to the missing data cannot be considered definitive.

Sorry to intrude again, but another most interesting plot. Plotted on the same graph is the OPR distribution for bridge, hybrid, and teleop. The way OPR is calculated (from lumped sums), it stands to reason that we should expect to see similar distribution shapes for any OPR statistic be bridge, hybrid or teleop. This is what we see.



Like one might expect, the elite tier teams dominated in Teleop. It is a little surprising to me that they do not also dominate in hybrid. Perhaps if we see some autonomous bridge jousts for balls this shape will change. In the middle of the road teams, it is clear that bridge balancing is worth more points than teleop and hybrid, although not by a terribly large margin. I also find the fact that the teleop and bridge balancing curve cross again near zero -- I wonder if this is a sign that teams with inexperienced drivers make it hard for their partners to balance, versus just being unable to score balls by themselves.

On a final note, notice all three lines are quite close. The game has a beginning, middle, and end and they are all close to equally weighted. I wonder if other FRC games that are regarded as good and fun to watch share this characteristic?
