IO Enhancement Math Not Working as Expected

[Firefairy]

I haven't gone through and poked at this a great deal, but I wanted to post before I forget. I slotted Distortion Field (Time Manipulation power), which has a recharge time of 1 minute, 0 seconds, with a Level 20 Invention Origin Recharge Reduction Enhancement, which says it "Increases Recharge Rate by 25.6%". My expectation was that the time for the power to recharge would go down by 25.6% of 60 seconds, or 15.36 seconds, leaving me with a recharge rate of just under 45 seconds. Instead, it is 47.77 seconds.

 

Am I just not understanding how this math is (intentionally) being applied, or is this a bug? If I am just not understanding, I would rather save myself the trouble of digging up further examples, but if it's a bug, I am willing to check the math on my other enhancements to see if this is the only example.

You've got the math wrong.

 

Reductions work like this:

• Base Duration / (1 + Enhancement Value/100)

60 / (1 + 25.6/100) = 60 / 1.256 = 47.77s

 

 

This means that a 100% recharge reduction cuts the recharge time IN HALF ... not to zero.
