How much does a player need to gain with hard training on practice match, cardio and stretching to be recognized as a fast trainer? Not exact numbers, but at average.
Take example stretching, on normal players gain an average of 10%, so on hard its double equals 20%. So when a player trained on hard gains 30-35% on stretching, does it makes him a fast trainer or should he gain 40-50% to be a fast trainer?
