Set up the equations like so:

The lower the number, the better the DPR. Like golf.

Possibly. The hardest part about DPR is that a low blue_alliance_score could come from two possible sources. It could be that one or more red robots are playing really good defense. But, it could be that the blue alliance has a very low combined OPR (read: needs better offense even without defense being played). Without having an OPR-to-score comparison built in, there is no real way to determine whether red is playing good defense or blue is playing bad offense.

You might be able to do it with

red1+red2+red3 = blue_alliance_OPR - blue_alliance_score

and the higher the score the better (due to the OPR-score) but that involves knowing the blue alliance's combined OPR.
