Hmm, so everything seems in good order, apart from maybe one thing. The best way that I can describe it is that there is a bit of "slop" in the derailleur itself. So I can manually push the derailleur a tiny bit closer to the frame than the current shift position - probably only 1 or 2 mm, but that'd be enough to throw the shift off.
I'm guessing a derailleur is not meant to be able to do this?
Any ideas what I can do to fix this, or is it new derailleur time?
I think that's by design isn't it. They overshift a little, which is why you have the limit screws. It's hard to tell without seeing it and comparing to one that's new.
