without a elastic effect, the player would be finished at the same time independent if you train the fast or slow skills first ;)
Age affects in the same way all the training,that's right.
But a pop comes when the player reach a certain sum of decimals,right?
That is the point,a slow training needs more weeks for a pop,and while the seasons pass,the age factor became stronger..If you don't reach the pop in a season,you had to do some training in the next season whent the training is less effective because of the age factor,and so on,so losing time
For example,if two players trained in the two opposite ways arrive at the age of 23 nearly at the same level,the player that had to be completed in the slower skills,could have to have some training in the 24yrs season,when a week of training is less effective than a 23yrs season training,while the player that had to be completed in the faster training can reach the pop before the season ends,so not losing some decimals because of the age factor of the 24yrs season instead of 23yrs
