holding grudges bugs

[pagpag]

Hello!
Holding grudges tactic looks bugged.
Tooltip says: every 4 seconds you gain a stack (max 3), each stack reduce exhaustive blows rage cost by 25%. Exhaustive blow spend 1 stack.

Bugs noticed:
1) I watch the rage bar (and amound of rage x/100 on tooltip). If you get 100 rage and 3 stacks, use exhaustive blow, rage drops to 75 (right).
But in most cases rage spent doesnt match the number of stacks.
Looks like there is different mechanics. If you have 3 stacks, exhaistive blow costs 25 rage. 2 stacks - 50 rage. 1 stack - 75 rage.
Examples:
a) Start combat. Gain 60 rage. Use precarious assault. Rage drops to 35 (wrong, should be 45, 3 stacks). Use precarious assault again. Rage drops to 0 (wrong, should be 25, 2 stacks).
b) Start combat. Gain 30 rage. Use precarious assault. Rage drops to 5 (wrong, should be 20, 3 stacks)
c) Start combat. Gain 40 rage. Use precarious assault. Rage drops to 15 (wrong, should be 30, 3 stacks)

2) Spending a stack resets cooldown of gaining stack
Example:
Get 3 stacks. Spend stack. Wait 3 seconds. Spend stack. You have to wait 4 seconds to get new stack (7 seconds total).
