It is impossible for anyone to answer this at this time (except the BB who programmed it and won't tell us).
I am keeping track of training in a way of minutes, and full trainings for several weeks now and still can't subtract any decent, solid info from it. I estimate it will take at least 2 more seasons before I can put something together that might come close to the right answer on this question. So for now it is guessing.
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
