people, I think most people overestimate the effect of crosstraining. Even when there is the expectation of one pop per player and training, which is not reasonable in many trainings such as rebounds and pd, and we are talking about 10% of the training value.
Which means, thought the other way around, we are about to see a random pop about one time in 10 weeks, but with a huge variance, because the subs have a strong effect here and its like to have the cross training in a slowly training field for the player (e.g. when there is center training, it will likely be something as pd, which is slow for tall players)
So everybody should slow down and stop expecting a huge amount of pops from crosstraining. Be happy when you see something unexpected, but don't get too used to it.
