The measurements I do don't tell me the position of the acoustic center. They tell me when each subsystem is aligned with one another. I'm always looking at the positions of the nulls, which is an indirect indication of the alignment of the acoustic centers.
As an aside, I've always despised the phrase "time aligned" when discussing loudspeakers or any other reactive system. The phase shifts and therefore the apparent position shifts too. But it's really just semantics. There is an approximate location that can be described and discussed, and phase shifts tend to move the acoustic center around that position.
