Actually I don´t think adding 0.01 would do any good.
If I understand the Crosstraining Concept correctly (which I doubt, as I´m not sure anybody does), it redirects 10% of the training towards other categories. But that means what?
If you trained Passing one position for a small player, you might get 0.45 training effect for a full week. Which is...how much? 100%? Unlikely, as there´s already some B-Skills down. So let´s say that´s 90%, so 1/9 from that (which equals 0.05 "Passing") will be shifted somewhere. And now all those questions ... is 0.05 apples the same as 0.05 oranges? Is all that elastic and size and age again considered, when applying it on another skill, making 0.05 apples all of a sudden 0.10 bananas or 0.0085 melons? How about 2, 3 positions training, and team, and...
