'proper' manual doesnt mean the ball goes exactly where you aim at the exact power every time with no factors taken into account. it takes into account players stats and your EXECUTION (not decision) is altered by those stats, so things like balance, power, accuracy etc will all be handled diferently player to player
the difference with manual and assisted is that assisted changes/overrides what buttons you press, whilst manual absorbs what you press and then (based on player stats) determines how well that action will play out. huge difference
In ideal world, what you described would be be the semi-assisted or semi-manual setting.Manual would imply that stats play a lesser role if nothing at all in the execution of passes and shots.
