Example graph interpretation:

81 - 18 = 62% of Alliance Unpenalized Scores were within +/- 20 points of the "OPR" predicted value.

66 - 32 = 35% of Alliance Unpenalized Scores were within +/- 10 points of the "OPR" predicted value.

The usual Twitter data caveats apply.

Attached is a cumulative percent histogram using updated Twitter data 16Mar2014 16:44:46

81.5 - 18.7 = ~63% of Alliance unpenalized scores were within +/-20 points of the "OPR predicted" (L2 norm) value.

Key:

  rw:	TRUE if red won the match, i.e. rfinal>bfinal
  bw:	TRUE if blue won the match, i.e. bfinal>rfinal
 tie:	TRUE if the final score was tied, i.e. rfinal==bfinal
  ru:	red final score with awarded foul points subtracted, i.e. rfinal-rfpts
  bu:	blue final score with awarded foul points subtracted, i.e bfinal-bfpts
 ~rw:	TRUE if red would NOT have won if there were no foul points awarded, i.e. ru<=bu
 ~bw:	TRUE if blue would NOT have won if there were no foul points awarded, i.e. bu<=ru
~tie:	TRUE if the score would NOT be tied with foul points removed, i.e. ru!=bu
 rwa:	TRUE if Red's official win would have been altered by removing all foul points, i.e rw && ~rw
 bwa:	TRUE if Blue's official win would have been altered by removing all foul points, i.e bw && ~bw
  ta:	TRUE if the official tie would have been altered by removing all foul points, i.e tie && ~tie	
 fao:	TRUE if match outcome was affected by foul points, i.e. rwa || bwa || ta

Thank you, Brandon


Here's an XLS version with practice matches removed

Has anyone located a lookup table with district event codes? and which region each district event is in?

Thanks!

Besides FRCLinks, you can download the Alliance Selection Spreadsheet and do a lookup there. It might be more convenient then parsing a webpage. For district events, the begining of the name contains the area, ie MI, NE, PNW, or MAR.
