After using Speed and Stamina by rinoaff33 for a new character, I found myself jumping too high and rarely ever needing to use a restore/fortify fatigue potion, which bothered me greatly, so I decided to make some personal tweaks until I was satisfied.

Reversed or tweaked several of rinoaff33's changes in order to reduce some perceived imbalances as well as to keep fatigue/stamina relevant:
 
-> Increased base running speed, but restored running speed per athleticism level to normal
-> Decreased effects of encumbrance on running only, not jumping
-> Running/swimming decreases fatigue very slowly, but enough so that you may still want to pop a couple of fatigue potions along the way when running between two towns if you don't want to rest.
-> Swim speed / waterwalking speed slightly increased
-> Base jump height is still slightly higher than vanilla, but much lower than original 
-> Sneaking speed same as original

Uploaded an additional .esp "SpeedandStaminaMB10" which adds the following tweaks:

-> Increasing walking speed of player and NPCs by 10%
-> Increases walking speed of creatures by 10%
-> Increases levitation and flying speed by 10%
