-What is new and old training?
it's the training in the new and the old version.
There is an older version of the game. You still can play in the old one (and many images and descriptions are from the old) but I don't recommend it.
There are many things to learn, so it will be difficult to learn those two versions at the same time.
I was fan of the old one -

but now I like the new because of the associations competition. Anyway, if they 'll fix some problems and RAM eating of the new one, I don't believe the old one won't continue for long time.


-How does playing games/friendly affect training (besides lowering fatigue)?
the players gaining progress (skills or sa/extra role)
A good 5* fast trainer is gaining +1 (and little more) after an official game.
Also +1 after a training of -18 condition drills
and about +0,6 after a friendly game
* +1 I mean, of the 50 for sa or extra role.
** I don't recommend to play friendlies in your level. Not worthy.

-I've sniped 5 fast trainers
good strategy. 7-8 fast trainers is enough (for "key" players )

Is this a good strategy?
first use all your players twice, to get the bonus and then only the fast trainers.
Attackers - attack + M&P drills , defenders the same

-I am at the training level 16. Should I focus on getting more whistles for specific practices
no, better go for a variety

We invested all our tokens into our field. Was this smart?
no, it was the worst investment you could do
