That is exactly the problem. OPR is calculated using all matches including surrogate matches. I would still want to calculate OPR this way. More data point is better even if the match does not count for that team.

Unfortunately team standing from FIRST website only adds up the total of the auto, teleop and climb points of non surrogate matches. This means when I solve A x = b, the matrix A contains the surrogate match while vector b does not contain surrogate match.

My proposal is to scale the value of b for the teams that have the surrogate matches before solving A x = b. Does anybody have any other suggestion?
