The summary on the right of the rune book rounds the ending values for some runes; are the decimals it chops off still in effect, or do we need to consider where the "magic whole number" values are when placing runes?
EDIT: Another completely unrelated question: Looking at what you wrote for the diminishing returns on movement speed, it looks like as you pass the "major" cap on movement speed, the "minor" cap is shrugged off, at least if I understood that correctly.
So if your final movement speed is 451, then it would use the major formula, which is 450 + (451 - 450) * .5 = 450.5 movement speed. If your final movement speed is 449, then it uses the minor formula which is 370 + (449 - 370) * .8 = 433.2 movement speed. That can't be right, can it? Or did you just abreviate the formula (i.e. the 733 movement speed used in the example was already affected by the minor formula) just to make it simple, and most people wouldn't care anyway?
