This used to work so well. The first times I used it I could just fix a couple of things and my edit was so fast. Now it seems to be random. It will remove things that aren't even repeated so they aren't "another take." Then it will leave two sentences or more that are clearly different takes, sometimes even when the wording is absolutely identical. And one rule that is probably right - unless you have algorithms that are doing things I can't see - the last take is usually the best.
