fortunately like some builders they did not cheat the BB drop.
It can be helpful to have more data points from different size Masis than just my 58. Seat angle as well as bottom bracket height + individual build differences can raise or lower the top of the top tube height. And as already mentioned how much slope the top tube has. Of course the size of tire can do the same. Just to be clear the 50 cm Masi (measured the Masi way) has a stand over height of about 29"?
