Moving uke is just as good as hacking the replay, don't do it or if you really want to at least keep it private.
Anyways to the replay:
Why did you contract the knee after the boom? It just made the hit powerless. Overall you have made it better, there are still some twitchy movement which doesn't look so good, as well as being overall a bit stiff, but you're getting rid of your random movement for the most part.
