Multiply wave suffering

I think I only gained maybe a quarter APS point from my multi-wave surfing. I'm planning on going back and working on it more in the future sometime -- first, to just verify what difference it currently makes, and then to see if I can improve it. I'm also curious how much of a difference multi-wave surfing makes in true surfing vs go-to surfing. My drive is of the go-to variety, though it may change it's mind once or twice per wave depending on the changing battlefield conditions.
