I don't see the reason why the probability of getting good rewards should drop if we get more challenges. If I remember correctly, upon completing Ultimate training, one would get 78 Tendo frags. And you would spend a great deal of time doing that.

Reset option seems reasonable BUT, that would make it same as Ninja Exam and without introducing 'sweep' *on, the Ultimate training feature would become Ultimate boredom killer.
