Your last Post is very good.

I had the luck that my Server doesn´t autosign SP´s (i only play via T11 Site from my main PC), so i was able to make a bit more Stats, from which i think they can help a little bit.

Last Year i bought a Fast Trainer named Eliot Cordova Gaete (5Star Nordgen without a SA) 18 Year old. I trained him Freekick-Spezialist and spend more Tokens to improve his Quality, because he performed well for me

Here are the Stats for his SP-gaining:

5 Star:

Training Stretching Cardio Practise Match
Normal 18,39 36,78 55,17
Hard ~37 ~73 ~110
Gaining per regular Game round about 105

6 Star

Normal 13 26 39
Hard 26 52 78
Gaining per regular Game round about 81

7 Star

Normal 9,48 18,92 28,4
Hard 18,92 37,84 56,76
Gaining per regular Game 54


This means from 5 Star to 6 Star is a decrease of about 30% of losing efficiency in SP gaining
From 6 to 7 Star the lose is about of 27%

It seems to me, that fast Trainers lose more Efficiency in Star winning then not so fast Trainers


P.S. This Season Gaete is 19, and started the Season as 6 Star and his Stats are the same as last year, he is now 7 Star (also the same stats as last season), so his Age doesn´t makes a difference yet
