Actually - looking at the Geo chart - where they appear to measure VTT from is quite far back from the seatpost? (Which would account for the extra over the actual top tube)

It's not the clearest, but in a roundabout way, they do appear to be measuring from the centre of the tube.

What's the seat tube angle on your current bike/s? Bear in mind that for every degree the seat tube is steepened, the same effective top tube would give you over 1cm extra reach.
