Three people I know scored low on the hand-eye coordination part of the test. This despite reasonable accomplishment in Pitts and Cessna aerobatics (requiring somewhat different skills, but both good hand-eye coordination), and vintage dissimilar-type formation (also requiring some stick finesse).
I tend to agree with Artie, although it must also be said that there are so many people applying that they can afford to turn away good people because the remainder are likely to be good. The danger comes when the not so good get through, either because they're good at those tests, or the standards are dropped. Then the filtering criteria becomes financial, and that isn't so good. In my opinion, that is.
