I go to 0 ADV as soon as I can in all worlds, and spend little to no time keeping track of progressions. I have played this game long enough to glance at a guy and know who he will be. You can even kind of determine this for first year players, by checking draft slots, which team drafted him, what their budget was, how much he signed for, etc.
As for rookie ball, I punt coach hiring there, and populate it with crap. All of my future higher minor league guys immediately go to LowA.
