Sounds like I forgot a *100. xPer lines need to read: xPer = ceil((xCur / xMax) * 100)

function(unit)
	local pCur, pMax, mCur, mMax = UnitPower(unit), UnitPowerMax(unit), UnitPower(unit, 0), UnitPowerMax(unit, 0)
	if pMax > 0 then
		local pType, pToken = UnitPowerType(unit)
		local pColor = PowerBarColor[pType]
		if ( (pToken ~= "MANA") and (mMax > 0) ) then	-- Druid in Bear/Cat form
			local mColor = PowerBarColor[0]
			local mPer = ceil((mCur / mMax)*100)
			local ShowPower, ShowMana
			if ((pToken == "RAGE") and (pCur > 0)) or ((pToken == "ENERGY") and (pCur < pMax)) then 
				ShowPower = true
			end
			if mPer < 100 then
				ShowMana = true
			end
			if ShowPower and ShowMana then
				return "|cff%02x%02x%02x%s|r |cff%02x%02x%02x%s|r", pColor.r * 255, pColor.g * 255, pColor.b * 255, pCur, mColor.r * 255, mColor.g * 255, mColor.b * 255, mPer
			elseif ShowPower then
				return "|cff%02x%02x%02x%s|r", pColor.r * 255, pColor.g * 255, pColor.b * 255, pCur
			elseif ShowMana then
				return "|cff%02x%02x%02x%s|r", mColor.r * 255, mColor.g * 255, mColor.b * 255, mPer
			end
		elseif pToken == "RAGE" or pToken == "RUNIC_POWER" then		-- Warrior / DK
			if pCur > 0 then 
				return "|cff%02x%02x%02x%s|r", pColor.r * 255, pColor.g * 255, pColor.b * 255, pCur
			end
		elseif pToken == "ENERGY" then	-- Rogue
			if pCur < pMax then
				return "|cff%02x%02x%02x%s|r", pColor.r * 255, pColor.g * 255, pColor.b * 255, pCur
			end
		else	-- Everything else
			local pPer = ceil((pCur / pMax)*100)
			if pPer < 100 then
				return "|cff%02x%02x%02x%s|r", pColor.r * 255, pColor.g * 255, pColor.b * 255, pPer
			end
		end
	end
