Training vs friendlies

[Mitja fc]

Well I checked history related threads but all info provided there is speculations...
I played few friendlies and noticed that I get more %increase versus tougher opponents so I will focus on playing similary strong teams...
Last game I gained +24% total increase it was win after extra times so condition lose was around 15%...it equals gaining +2% per training session per player...majority of my main squad is above 100% and all are over 90% so training probably wouldnt be as effective...I have cca 160 blues and reds
I will use greens on fast trainners...bought one on auction for 2 tokens he was probably trained at end of last season cuz he had only 56%...he is DR I trained him def.heading attribute he gained +7 per 6 sessions with 13% condition lose and is now gaining cca 4 to 5% per training session...so cca 200 rests will be needed to get him on decent level...will get another one in 2 days from youth academy for whom I will also need atleast 200 rests...

Hopefully I will get enaugh rests till end of season to get my team on 100% in next season if not I will just tank it

EDITED: he is 18 year old so he came from youth this season xD
