Training vs friendlies

[ponzu]

I have a full stadium of 260 K' and earn 10-12 M' from one game.

I can't fill the stadium for friendlies unless I charge $1. At $2 I get 0 attendance, even if I invite a high level team. How do you get 10-12M? Do you charge $50/ticket?

the best for me is training in 3 bars

Simple math question: whether you went two rounds of training at 3 bars, or three rounds at 2 bars, do you feel you would get the same SP and burn the same amount of condition? Or does one scheme provide advantage over the other in terms of SP/burn?
