I have just uploaded a
scouting database which contains component calculated contributions. Since component OPRs seem to have the property of linearity (although I don't fully understand why), it should be easy for anyone to play around with these. Currently, I calculate eOPR using method 1 described in my original post. That is, eOPR = (total points) + 3.125*(subtracted tower strength) + 2.5*(cross defense count).
