If you extend Int up to 950, the 910-900 rated players would be in a crappy position you talk about low rated Adv players being in. If you created another higher level of Am, it would just be a couple of people you want to filter out of a division.
Of course the difference between a 970 and a 940 rated player is like 3 strokes a round on average so it is not like there is some crazy discrepancy going on in adv. If a 940 rated player wants to compete with that 970 rated player, they should figure out where they are giving up those three strokes a round and fix it.
If a dude gets rated 940 after his first tourney, he might be stuck in Adv for a couple of tourneys but if he is really a rec rated player, he will shoot to his rating and go down to where he should be. I have no idea what that example has to do with what we are talking about but something something statistics small sample size etc.
the difference is that the people that are 945-949 are going to get better and have to move up. as it stands a player who is 935 could play against a 997 rated am. thats 6 strokes per rd. Im also for the trophy only Am system. and not Baskets as trophies. actual little plastic discers. that would motivate everyone to move up.
