Sorry to say this my friend, you understand it wrong but it isn’t your fault.
Let’s start from the beginning. Condition has nothing to do with training/raise of a player. Performance/rate of the player also. Anything you read about condition in this thread forget it.
The gaining (raise) ability of a player depending on some characteristics he has when he comes out in the market (or from an academy). All the young players (18-21 y.o.) train better than the olders. Some of them doing better and some are top.
If you want to detect who are the top fast trainers, check this guide (it’s mine, in my signature) and this one of Khris.

It’s not so simple, that’s why many players don’t have a clear picture but if you understand it, it has very “clear rules” unlike others issues of the game that 2-3 years exp. managers still cannot be sure.
