At the turn of the millenium, the allocation was about 30hrs - ie 90hr course (as you say) but the average could be higher because of the monthly 'Essential Exercise'/currency trips.
Then someone had a brainwave to reduce the EFT cse to about 70 hrs by taking out most of the confidence-building solos and capacity-enhancing fun trips like tailchasing and LL Nav and composite sorties towards FHT.
Consequently, it is more difficult for QFIs to assess the studes potential capacity (this from the horse's mouth on numerous occsaions). Therefore, streaming is a bit of a lottery for the studes.
This hardly makes the system more efficient - both streaming at UASs and the introduction of EFT on UASs were large backward leaps.
