I might be wrong, but tags don't profit from frequentUpdates, afaik. A normal health function would do it, though.

Edit: something like this

local updateHealth = function(self, event, unit, bar, min, max)
    local d =(round(min/max, 2)*100)
	bar.PERvalue:SetText((round(min/max, 2)*100))
	bar.value:SetText(min)	
	bar.value:SetTextColor(1,1,1])
	bar.PERvalue:SetTextColor(1,1,1)
end

or

local updatePower = function(self, event, unit, bar, min, max)
	local dp =(round(min/max, 2)*100)
	bar.value:SetText(min)
	bar.value:SetTextColor(1,1,1)
end

note: just examples, nothing that insta-fits into your layout
