Rigged Training, Lesser Learning??

[snowsub]

I'm not too concerned about avoiding timetables and delays, it is an exercise after all, but to have things re-done, just so a favourable outcome can be achieved is a little on the nose.

It's like playing hide and seek and when you can't find someone, redo it and make them tell you where they are.
How are the soldiers etc meant to learn in those circumstances?
