NED dude...Train the high altitude stall with ADR 1-2 switched off, or better yet, put ice on the respective pitots and watch what happens......particularly watch the THS reactions.., you may find even full nose down commands, while causing the pitch to be reduced, does not reduce the AOA sufficiently to "break" the stall, large amounts of nose down trim wheel inputs may be needed....food for thought...
As for the main topic....I suspect more hours rest, rather than more hours in the logbook would be more on target...but that costs the industry money so not like to happen...as usual lay the problem at the feet of the pilots...
