Yes, anything is possible Tim! This has been requested a few times now, and it’s something we may consider building in the future, but it’s not being developed yet. If you come up with a calculation that seems to work, then we would love to hear about it!
TBH, using the course rating to balance the players would be ideal, but we don’t need it for a first pass. All we need is a rough X points of rating difference = 1 stroke bonus. X probably needs to be bigger as the player averages go up? I don’t know exactly how that all works.
Using a course’s “par rating” and comparing it to the typical +/- average round yields a value of about 3.9 points equating to one stroke above or below par. That didn’t work out when comparing two players’ ratings.
So…
I took the 10 most recent 18-hole rounds my son and I played in common that yielded ratings (several courses we played were either fewer than 18 holes, we skipped a hole or two, or they didn’t have enough plays to generate ratings). I had to go back surprisingly far. Anyway, my son has an average rating 22.3 points better than mine in those 10 rounds. My scores were 7.8 strokes worse than his. This seems to equate to a stroke for every 2.86 points difference in our ratings. Whether this carries over to “everyday” rating, since that calculation cherry picks recent stellar rounds (read: when we played easy courses), I don’t know.
Granted, our averages are very low so I don’t know if that really means a 250-rated player against a 90-rated player would need to give a handicap of 56 strokes. Personally, I don’t think that would come close to enough strokes to spot the lower rated player.
