I don't think that's necessarily true. The same factors that would tend to cause front-focusing or back-focusing with any particular lens while autofocusing would still be, I think, in play when manually focusing, too. (That is to say, when manually focusing on the focus screen, whetehr using a split image or not, if the registration distance is wrong for that lens, it would be wrong for both MF and AF.) No?
