SUPT washout rates have a lot more to do with the objectives of the AETC leadership than anything relating to student performance.

SUPT leaders are measured by their pass rates in SUPT. This leads to things like students who are re-instated by CRBs 2 and 3 times after failed 89s. We had a kid go through IFF who had washed out of Vance so many times that he had to be re-instated at Columbus because the Wing CC felt he could no longer get a "fair shake" at Vance!!!

Yeah, no kidding. Washing out three times tends to make IPs, Squadron Sups, Check pilots, etc, think that you don't belong there.
