Background of students. There were so many additional sorties that in reality the course was under resourced.
Pilots that haven’t hand flown much since pilot training did not do well in a syllabus that was originally primarily designed for 11Fs with a smattering of 11Bs
There are now front seat contact (transition) and formation progress checks before rear cockpit flying after in the IQ check. UIPs that can’t hack it are cut before wasting resources.
