You are totally wrong a few points.
I agree,
You are totally wrong ;-)
#1 We do not know
1st of all - You don't know. "You" isn't "we" ;-)
2nd of all - if You don't know how something works it doesn't mean that it works in way You think (or want) and it doesn't mean that it doesn't work in way I think ;-)
#1 We do not know that the crosstraining, which has been explained, works the exact same way as elastic effect and secondary skills
It was described in announcement and it works in the same way.
It is that quote:
In the past, coaches would teach a new skill (such as driving) using related things players already knew how to do (such as handling), so that players with a higher handling skill would learn driving more quickly, and players using this method to improve their driving ability would also learn better handling, at a slower rate.
With cross-training, these new techniques emphasize each skill as part of becoming a more complete basketball player, and make reference to every skill. Thus, improvement in driving is related not just to related skills (like handling), but also more weakly to unrelated skills (like shot blocking).
a. elastic evaluation is not random, nor is the application of secondary training
Effect of crosstraining isn't random as well.
Your examples and calculations. It means that if somebody has well rounded player then he will receive penalty because he can't train him as fast as one-dimensional player. It has no sense. This change was implemented to help to create well-rounded players, not to penalize managers who have well-rounded players ;-)
I believe elastic effect changes distribution of training, not increase total effect of training.
