With this patch, the target's health percentage shows one decimal. So you'll finally know how much that 1% wipe *really* was.

XPerl\XPerl.lua
Line 8, ADD:

local percF	= "%.1f"..PERCENT_SYMBOL

Line 708, REPLACE

			bar.percent:SetFormattedText(percD or "%d%%", (percent + 0.005) * 100)

WITH

			local fmt = percD
			if percent < 1 then
				fmt = percF
			end
			bar.percent:SetFormattedText(fmt or "%d%%", percent * 100)

Thought about this a couple of times. The 1% mystery is not so bad now that the real health values of things were exposed in the API some time ago. Will see how it comes out on screen later.
