What is the total conditions cost threshold to be considered as power-training?

I don't really understand this question, however for me it is power-training when it is not bonus training. So whenever you decide to train a single player and select appropriate drills for him individually, I would call it power training.

With power training, typically we would be putting lots of greens, sometimes from tens of greens to even hundreds of greens, onto 1 player with specific focus in specific whites.

And usually the trained player would underperform a few matches after these training.

My question is what the maximum number of greens (conditions) used and still would not trigger the underperformance issue.
