Heroes 6 - Discussion

The thing is that morale in all heroes affects the movement range; the question is, to what extent. Previously, it was limited to the number 10, now it's 100.
To clarify the question: is it possible to increase a hero's movement range on land by 3-4 times using in-game methods (not codes/cheats)? By how much, for example, will +40 morale increase the range? Or +100?
