New + / - Metric To Measure Impact on Winning

I frequently manually calculate my + / - score for games. This helps me understand how well I played overall.

As a fan of other sports, I think it is more intuitive than the Overall Performance Rating.

My definition of + / - is:

1) Did I cause us to win or lose the point, by either hitting the final shot or hitting the set up shot.

2) Did someone else just hit a great shot with no fault by me?

3) Was it just an unforced error by someone else?

    For v1 I’d start with: did I hit the final shot on my team and win the point (+1) or lose the point (-1), did I hit the penultimate shot and win the point (+0.5), or lose the point (-0.5). Determining whether you hit a good setup shot or not seems pretty tricky for the ML vision system.
