Camera Recoil recovery isn't reacting as predicted?

So I am using a fully pathed script for making artificial camera recoil:

RunService:BindToRenderStep("cameraRenderUpdate", Enum.RenderPriority.Camera.Value, function()
		if tick() - Last > FRate then -- Artificial DeBounce.
			if Shoot == true then
			print("Shot")
				local X = math.rad(math.random(May/2,May))
				local Y = math.rad(math.random(-Max,Max))
				local Z = math.rad(math.random(-Max,Max)/4)
				Target = CFrame.Angles(X,Y,Z)
				Recover = CFrame.Angles(-X/1.1,-Y/2,-Z)
				Last = tick()
			end
		elseif tick() - Last > RRate and not (tick() - Last > FRate) then --Check if it is between recovery rate and the fire rate.
			print("Recovering")
			Target = Recover
		elseif tick() - Last > RRate and (tick() - Last > FRate) then -- If it is beyond both.
			print("Ended")
			Target = CFrame.new()
		end
		Cam.CoordinateFrame = Cam.CoordinateFrame:lerp(Cam.CoordinateFrame*Target,.1/2)
end)

When the Fire button is held down, it works as predicted, you have some difficulty in keeping the mouse on point. However, when you release the button, you are still in the "Recovery" phase of the recoil. And you just carry on rotating in the recovery direction.

This isn't mean to happen, the 'target' is meant to be set to 0, but "Ended", never prints. Just Shot and Recovery. This is really annoying. Could anyone help?
