No. You can't find the per-match scores for Coop, Auto, RC, Tote, and Litter from the data FIRST provides.

You can find an estimate for the OPR for each of those scoring components as follows:

If [A] is the 2MxT binary matrix of the alliances (constructed from the match schedule), and [d] is the Tx5 vector of the Team Rankings component scores Coop, Auto, RC, Tote, and Litter, where M is the number of matches and T is the number of teams, then the OPRs for Coop, Auto, RC, Tote, and Litter can be computed by solving the system of Normal Equations

[A^T][A][OPR] = [d]

... for [OPR]


In fact, that's how it's currently being done this year (with some additional tweaking to account for surrogates and DQ's).
