The damage from legacy to UPT 2.5 in the T-1 was more in the grading and less in the hours, IMO.
The syllabus was shaved a bit, but the bulk of the bell curve could keep up. Those who couldn't keep up, obviously resulted in more 88s 89s. Those failures were retained or pushed to stay, which resulted in a climate of "no matter how hard we grade, leadership will graduate them anyway" which in turn leads to easier grading. You can talk about holding the line, and lots of IPs tried. But at the end of the day leadership isn't sending that message. Only worse now with T-1s gone. The sim syllabus was an absolute joke.
