Can you give us an equation or explanation of exactly how much...

The percentages in levelling up the training facility actually effects the players? The percentage on players do not change, unlike the infirmary. For example, if my player's training percentage is 100 %, how much difference does it make to level from 275-300 % for that player?
Thanks!
The amount of training points earned depends on several things :
- the training duration
- player's energy level
- player's training speed
- training facility level
Does this also mean that you only gain the training advantage when you use the training facility or does it apply to experience gained in matches (other than friendly ones) ?
It appears that it does not apply but I wanted to know for sure.
The training facility bonus is also applied for training points earned in matches
