Maybe... I'm really interested, how long (age) it works like this.
But it's not only the drill, also the match. AML (22 y.o., no FT) gains around 4%-6% vs weaker opponents. In cup he always gains 6-10%. Also my wife had an worldclass AMC (25 y.o. also, no FT), who gains nice (from 87% to 111%). At old version, he only gains ~25% per p.m.

I started few days after new Version, so I didn't know, there was an old version. Few games before season ending I searched on the internet, how much time between old and new season is. So I "found" this forum, read some thread and formed my squad. Used old version to check out, if it's a fast trainer. If it was, I learned them what I needed and was on with new version because of the bonus.

But sometimes, I made incredible stupid trainingsessions, f.e. Had a game vs 2nd on League (2 points behind me), made a hard session and had no green packs. The squad was around 40% condition and I lost 0:2.
Second game I won, so I won League one point ahead. ^^

If I win the league days before season ending, I doesn't matter on condition and just push trainingslevel.


PS: A full squad helps to push it.
