Also, it's not really just 25 greens. You can get another 5 "free" condition boosts on a specific player once the 25 video's are done. That's ~3 greens per player (~45% condition) plus the 48% free improvements during the day (6% every three hours). So you can basically drain a player from 100 to 0 through games and training every day and get him back to 100% essentially for free. You have to be on top of things, be efficient, and make strategic choices, but it can be done. Work smart, not hard.
