I don't think standing stationary is all that required. I usually circle WITH the horse, though in a tiny circle. You can move off to one side. In fact, sometimes if I am lunging (free lunging in a round pen), if the horse is looking outside , away from me, I might just edge my body back toward his rear. Not straight toward him but in an arc, as if I am going to walk out and behind him. He will turn an ear and an eye back toward me, and as soon as he does, I shift and begin circleing with him again. It's a way of getting his mind on you.
The shaking of the rope should always get some kind of response. So, if you shake the rope a lot, and he does nothing, and then you stop shaking it, you increasingly make him desensitized to that. IF you shake the rope, you MUST get a change. If he does not slow down, then make him stop and face you. You could not get a response from him because he was tuning you out, so you must get his full attention (him facing you, eyes (eye) on you) THEN direct him.
He looks much stiffer going left and even the tiniest hint of being off, which I know you had some concerns about. But, he canters nicely on the lunge, so you know he can do it.
When yoiu are leading him out to lunge, be sure that he is respectful of your space. And when you start him, don't back away from him to get him going out there; make him move off of you, out on the circle and then walk on forward. It's important to never back up .
