looking at OPR across events

[ErvinI]

My opinion on this:

CCWM within a regional: theoretically excellent. With the amount of opportunistic defense this year along with the frequency of fouls, this stat is stronger than OPR in calculating your strength since CCWM takes into account both offense and defense. However, looking at the GTRE rankings at a glance, CCWM seems to be all over the board, most likely due to the somewhat random nature of fouls.
Adj. OPR at a regional: theoretically excellent. There is some very large variations in terms of how many fouls your team gains. In fact, I am getting a standard deviation of 11.7 at GTRE. The issue with this is that some teams are more natural foul magnets than others due to their reputation (1114 has the highest foul OPR at GTRE).
OPR comparing robots at one event: decent. It's like Adj. Opr with even more error.
OPR/CCWM across regionals: horrible. Too many regionals have alliances that barely function, while others have too many alliances that function only defensively.

Has anyone done an Adjusted Contribution to Winning Margin analysis? That should be calculated as follows: ACCWM = (AOPR - DPR), iir the CCWM formula correctly. It should be able to take into account any fouls you incur while eliminating opposing team fouls.

Before anyone says it, I also agree that this stat will also have to be taken into account with a grain of salt, due to alliance synergies, luck and what-not.
