You always get points in any sanctioned event even doubles and match play. You can get ratings in an X-tier at any level depending on the format. If it's Super Class you get Super Class ratings. If the X is for mulligans or stableford scoring, then no ratings. Glow format or graduated entry fees, you get ratings. Basically, if you are playing straight singles golf you get ratings.
If you have 5 propagators playing the format, you'll always get ratings. If you have less than that, we will try a few ways to get them. If say 3 players are props and you play the same course layout twice, that's like having six props so ratings will be calculated. If we can get the course length and foliage density, we can compare the manual calculation with a limited prop calc and come up with something that's fair.
