[B a player would gain progress 5x quicker in a very hard drill than in a very easy one?][/B]
id agree 100 % with that,if trying to bulk up my % ill just use all hard but usually train in 2 gos, one defense using the zonal to pick players from GK-DMC'S then an all attack with Midfielders to Strikers making sure each time working from very easy-v hard with each one
