In the Mark Vaughan's guide, it is said if the bar is at the highest point, it means that the player has reached his maximum limit in that category.
I translate that into: "If the training level in one category is maxed out, there's no need to go over that, that's a waste, let the player train more in another category."
But
1. How can I tell that a player's attribute is at the maximum from training already?
Does the top dotted line equal 100%, if so then I have several players going well over 100% right now.
2. If you have a player training at 100% in a category, how do you ensure he always train at the optimum level, no more, no less?
