Stability criteria usually include something about spooled up engines, complete checklists etc. In the companies i have flown in on the 737 it was allways at least 40% N1, on speed, on final configuration, checklist complete. That is not only expected during training flights but during normal line operation as well. However during training flights it would be expected to be even more go-around minded than usual, nothing is worse than showing busted limits during training as the trainee usually gets the impression that there are differences between book limits and "real" limits used on the line. A very dangerous thing in any airline.
I'm really looking forward to the final report and hope it was completed as free of any political pressure as possible.
