Hi!
In Air Force UPT we did 2 flights a day when we could fit it into the schedule.

PS-I agree that I think the major factor is if it is helping the student, then do it 1,2,or 3 flights a day, whichever is best for them. More flights, if they can absorb the info, means a more continuous learning curve, and less money wasted repeating stuff. Do what is best for the customer!
