How do you calculate %xHKO?

One thing about this I was thinking recently. For magic damage considering defense, the defense can have a multiplier of 0.5 to 0.6 meaning that the most extreme values of your damage range have a lower priority than those in the "middle" since they need to combine both the probability of being at the extreme of the uniform distribution AND the extreme of the defense multiplier.

So the distribution wouldn't be exactly uniform, it would have some rise/fall on the borders (don't know if that's what Noah was talking about but this caught my attention).
