I agree. I just think that in this range a change of 11 points doesn't buy you much. Like I suggested above, I think it's a fraction of 1%. So for a guy that took 216 2 point shots, if you put the over/under for how many fewer baskets he would have made this season with 31 PER instead of 42 at 2 baskets, I'd take the under. I think the point value of what you could have gotten from better passing and FT% with those practice minutes would have been more significant. But it's all pretty nitpicky, and a fraction of a PPG in difference probably doesn't matter very much in most cases. It's also hard to predict - I don't think either of us has enough experience with low-WE players to predict that the guy was going to grow by 11 points in PE in his career. If it had been 20+, it might be entirely different.
In retrospect, would you change anything about the practice plan you generated? Or are you happy with how it worked out? I assume questions like that are the real purpose for this thread.
