OK, a 62 as the hot round in the morning will be rated differently than a 62 that is 5 off the hot round in the afternoon.... that is, if the same propogators (players) play the round. Conditions do not account for the factor of good old luck/skill. A player who averages 930 but shoots the round of his life of 1030 will bring all the scores down as his is vaulted up. It's the law of averages. If 10 people have 10 apples each, and joey ends up with 19, then everyone else will average 9 apples.
How you like them apples?
