He means messing up due to constant movement. If you are messing it up on a dummy, yeah then there is something wrong anyway.
My opinion on the question though, know the fights. Know when you will be able to stand still and try to create an opportunity for weaving at that point. If you will be on the move for an extended period and you have 4-5 orbs, go for regular cop and build up an opportunity for weaving next 4 orbs.
