I have been in game trying to obtain the formula for movement speed, and this is what i got:
 * 1) .-To obtain the raw movement speed (before dimishing returns) at any given time you have to:
 * .- sum all flat movement speed bonus to obtain BASE MOV SPEED. The flat modifiers are: the champion's own base movement speed, the boots, Sona's E aura, Singed's Ultimate, MF's innate and Vayne's innate.
 * .- Sum all percentage based movement speed bonuses (Runes, Items, Abilities) togeher. Ex: 8% from Zeal, 55% from Time Warp and 15% from Prowl. Then it is a total of 78%.
 * .- Now you multiply the BASE MOV SPEED for the percentage based (the 78% from above) and you got yourself the RAW Movement Speed. This is before any slows and dimishing returns
 * 1) .-Now I am having problems applying the dimishing returns. For quantities that are less than 415, there is no dimishing formula. For quantities 415-490, I just multiply the excess of 415 for .8. The problem is with quantities above 490.

So I need your help obtaining the formula. These are the values I obtained in-game: The BASE MOVE SPEED for all values is 455. Next I will give you the percentage multiplier I used, the raw move speed I got by using the calculations above and the value that my character actually got.

Percentage-Raw-Real

(08%)- 491.4 - 476

(08%)- 491.4 - 476

(08%)- 491.4 - 476

(20%)- 491.4 - 476
