Karthik, don't selll yourself short. I ran some regressional linear-bearing algorithms, and i find that your data is 97.234% accurate.

FYI, the Las Vegas Regional "Team Standings" data on FIRST's web site is incomplete. Every team played 11 matches, but the data does not reflect it. (Team 987 was 10-1, not 9-1) The "Match Results" data is accurate, however.

Trent,
It was due to a red card you folks got in the last quallification match right before lunch. I had asked about it and thought incomplete as well.

However, MSC is just a complete statistical aberration due to the overall strength of the state of Michigan, and the exclusive nature of the event. Most other regionals never really got to the point where they reached the point of diminishing returns of tube scoring in qualifying, or never consistently had three scoring robots on a qualifying alliance. What we saw more of was many weak regionals where only 1-6 teams could score effectively, as such there were considerably lower scores. (Events with elimination matches where only 7 points were scored, etc.)

I think that linearly scaling the entire average contribution or OPR skews it too much at weaker regionals. Based on the two events 330 attended, Arizona was much weaker then LA, as the statistics show. Our performance was also worse at Arizona. With the current scaling, the Average Offensive Score scaling is 113.7 at Arizona and 79.5 at LA. The Arizona value is very much over inflated. I think a better scaling would be

normalized value = (team - regional average) + worldwide average

This results in an AZ offensive score of around 67, which makes sense to me. This way you're only compensating for the regional difference, and not the teams performance.

Thank you to Geoff Allan, Ben Bennett and Roberto Rotolo!

Another year, another great 1114 database. Thanks guys!

It appears that the North Star (MN2) award data is missing.

Glenn,
Red card was withdrawn with appeal following the match so calculations would be just slightly different as a result I think...

Joe,
sorry for the inaccurate post.
I bet they didnt update it since it was the last Qual. match of the tournament.

Thanks so much!
Also, to just let you know: there have been new teams added, they are on usfirst.org now.
