Let's say that after first training CT affects JR; since PA is much higher than JR, CT will affect JR in stronger way. Let's say PA of your player will receive 87% of training and JR will receive 13%.
Second training: CT randomly chooses OD. Since PA is much lower than OD, also CT will affect OD less. Let's say PA of your player will receive 93% of training and OD will receive 7%.
Thanks for the very clear explanation, but I still have a doubt.
Before CT was introduced, it used to be that if you train a skill with a much lower value as compared to similar skills, the trained skill would train faster than "normal".
Example: JS = DRI = HND = 17, Pass = 12. Pass used to train faster than if JS, Dri and Hnd were all let's say at level 8. Is this still true? Because in your example you only mention percentages of the training but not its absolute contribution.
I know your reply was about CT (although the question wasn't) and not about elastic effect, but the two effects mix... or don't they?
