Re: 2014 OPR After Week One Events



OPR Distribution for unpenalized score data set Week 1 from Ether.
Distribution follows typical FRC trends as expected.
This appears to a game independent phenomenon, it is essentially the same in every FRC game I have ever studied. The game design affects the scale and the zero crossing point, but the curve shape is always pretty much the same. The GDC does not seem to realize this when they set the penalty scaling.

Count = 360 Teams,
Average Score = 19.0
Median score = 13.1
Max OPR = 91.6 (Go Bees! )
Min OPR = -13.0
STDev = 19.6
SNR = -0.3

The Average OPR is less than one standard deviation above zero.
A single technical foul is worth more than 2 matches worth of average team contribution. This is completely out of scale with what is appropriate for penalty scaling.
