Early classes for all the squadrons fresh from transition had it a little rough but the real variation seemed to come when they un anchored a squadrons NSS.
There is a lot of truth to this. I was one of the first few studs in a VT squadron to complete the T-6 syllabus and a friend who finished from the same squadron a year later finished with the same multiple (1.17 or .18 I think) and his NSS was 10 points higher than mine.
