Let us do a little mathematics: in the ideal conditions, outside shooting is supposed to give you a pop in jump range every two weeks while jump shot is supposed to give you a pop in jump range every eight weeks. So, outside shooting gives 50% of a pop and jump shot gives 12.5% of it.
By now, my player have received 325% (6x50 + 2x12.5) of what is needed to have a pop in ideal conditions. Since he hasn't popped, he has received, at best, 30.76% of what ideal conditions training gives. And that is if you consider that when he popped to strong, he stopped right at 8.00.
30.76% of the full training, once again in the best case scenario, is a little disconcerning for me I must admit...
