The NTRP self rating guidelines seem to suggest that under 25 years old division III player (It says NAIA - is that the same as NCAA?) Should self rate at 5.0 I found a player that self rated at 4.0 and had pretty easy matches except for one in league (went to tie breaker) and another close one at states (He won it 6 & 4). It looks like he may have registered as a 4.0 before signing with his Division III school and then played this year at the school. So far he's 3-0 at Singles line 4 as a freshman. Is this an oversight of the self rating system?
