I think it is a good starting point, and the main weaknesses have been pointed out. Namely inaccurate (usually missing) info, and hooked students. Having a good GC who can help interpret the data or explain anomolies should somewhat address the weaknesses.
A weakness going forward is going to be the TO kids. I know some have their early and unsubmitted scores showing. So for example a girl who was ED at Yale with a 28 ACT. Obviously to the obsessive CC crowd she did not submit that score, but others may not realize that and think that Yale is open to taking unhooked kids who submit sub 30 ACT scores.
Again, a weakness that a good GC can help with.
