I don't think that gameshape training is unrealistic (like hiring a "mental coach" - is that a word? or a Psychologist specialised for professional athletes is common among professional organizations these days), I would remove it completely though.
As I said before on the very same topic, I'm in favor of limiting it to X times per season.
Please don't do this - we don't need another lukewarm compromise that makes everything more complicated or might even be another source of bugs. Keep it simple just once every couple years. Leave it or remove it.
