T&G are you saying that your approaches are at a constant angle now, but you vary the speed as you fly down by altering the throttle? Apart from wondering why you want to vary the speed if your descent path is correct, I think you might actually be doing it the correct way without realising it. I always adjust my touchdown with the throttle, I keep the ASI steady with attitude while I'm doing it. Are you perhaps describing the same thing in two different ways...?
