(Edit) Looking at that chart again, I am not sure how to interpret the numbers. As I said in the initial post, my 118mm by measures 20.5mm on the drive side, not 25mm like it says on the chart. So either the specs have changed or they aren't measuring the same way I am. Perhaps their measurement is the exposed end of the spindle, rather than the distance from the flange.
I think there is a reference point on the square where it is a certain dimension. Thus the "stub" could be longer or shorter (to some degree) but the crank doesn't know better.
Maybe you can figure something out from this. look at page 9-
