I agree that recruits in contact with coaches will typically get more direct information, but it could be useful for a potential recruit who’s not quite to that stage yet.
That said, interpolating from the CDS numbers, fewer than 3% of Stanford admits have SAT scores of 1700 or below and if I recall correctly athletic recruits are around 15% of each class. So scores at that level are unusual even within this group and I assume would tend to be found among recruits at the top of a coach’s list.
Similar but less formal than the system in Ivy League football, which has four academic index bands and a certain number of recruits allowed in each band . . . those in the bottom academic band are usually going to be star players.
