Not sure, but I can test mine out and let you know! From everything I read, I thought it was supposed to be sharpest at 70mm even beating out the 70-200 II ?
Not at the edges from what I saw. The best copies are very, very good f/2.8 center frame at 70mm though (better than my 70-200 f/4 IS at 4, 70-200 2.8 non-IS at 2.8 (or 4), 70-300L at 4) but the edges on FF were more like the 70-200 2.8 non-IS and not a match for 70-200 f/4 IS or 70-300L.
The copy that I saw that was weakest wide open did 70mm f/2.8 roughly same ball park as 70-200 f/4 IS at 70mm f/4 (granted that is the weakest spot for hat lens) and worse than 70-300l 70mm f/4.
I have only had the lens for a few weeks, but based on my limited testing I would rate my copy as excellent (center frame) at 70mm and every bit as sharp, if not sharper than my 70-200 II which I would never have thought possible. The sharpness at the edges at 70mm is very good. I have not done a lot of testing at 24mm but what I have seen so far is fantastic center frame.
