Endurance discounts, lower values?

[Hitback]

Why is it that endurance discount appears lower in the combat attributes? 

 

For example I have -10% from support hybrid, but the attributes show it as -9.08%, 2.5 from the new Cupid set is listed as 2.43%.

I'd have to double check some code, but the math seems right.

 

Say end cost is 100.

You get +10% end cost reduction.

100 - 100/(1+10/100) = 9.091

100 - 100/1+2.5/100) = 2.4391

 

I think there may be some other factors, but that's pretty close to what you see.

That math is kinda counterintuitive and derpy, like most of the rest of the math in this game. In a logical world, the + sign after the 1 should be a - sign, which would make the end value be what the tooltips say it should be. 

 

Ex:

Base End * (1 - (All Discounts / 100)) = New End Cost

 

For Base Cost of 100 and Total Discounts of 10%, I would expect it to look like:

100 * (1 - (10/100)) = 100 * (1-0.1) = 100 * 0.9 = 90 Final Result.

So the attribute window is trying to show that they stack multiplicatively?

 

That's very odd, though, because recharge bonuses work the same way, but the window just shows you the raw values.

I think the display is off on some of the values and it gets more weird when incarnates, etc... are involved.  I'll see if I can dig into the score code later.  (which of course, could have changed in the last six years)

Mez resist bonuses have the same weird quirks. It doesn't help that the combat attributes values for those are displayed in a different format than how powers which actually give mez resistance display it.
