Re: Should have not used auto focus. Should have focused manually on the same point.

It is possible that you relied on slight variations of AF.

like how much off are we talking about here? like focus in one of the corners or at the edge of the frame?

if the center focus can be off, what makes you think that the spot focus is any more accurate?

The only way you can be sure, is to eliminate room for error. It is why you should identify the exact point and focus manually, then draw conclusions from it. Kaku's recommendation for using tape is also a good idea.
