You can look in the replay file to see where it was edited at, which frames, and what joints were changed. It's all in there, in plain old text, you just have to know how to read it. Being an old pro, deady can certainly handle a simple check like that ;) does that answer the question? Also, the problem might have been using uke vs tori in your replay. Did you try switching it? They have slightly different masses in different areas. Over one move it doesn't show much, but over a long spinning survival challenge it could be very significant.
