10/week is just a reference,used only for compared with the other age player.
as i said:no considering other influence on training speed except age.
i just want to know a relative ratio on training speed at different age.
a rough estimation is ok.
just like i ask how is the diffierence between a 7lvl trainer and a 6 lvl trainer.
from the increasing % on the salary,the 7lvl trainer's salary increasing speed is 2.5%,and the 6lvl trainer is 2.25%.
I guess ,if the 7lvl speed is 10 and the 6lvl is 9, although i know bb-forrest put logarithm to use in many environments.
