now I'm curious.. if I get someones MR under 0, and have % reduction, would it actually be bad for me, or is it not calculated at that point? if I say get their MR at -10 and have 40% reduction, would it get it to -6 or something?

on a side note, although it is applied last, and gets less effective, you still get a better overall reduction. 60% of 80 is less than 60% of 120 or something like that.
