Hello Vi,
I think that this could be right but one is not directly caused by the
other. Like Gerald said, if the axis from the seat to the bb moves up at
the front, it crosses the pivot axis with a bigger angle. If you wanna move
a hinge it's easier this way too. It's hard to move a hinge when the force
direction goes parallel with the hinge axis. So a bigger seat bb difference
maybe needs a flater pivot angle but not 1:1 because there are some more
influences too like the weight stuff from Olaf and Jürgen. The python is a
multiple parameter system where some guys have good results with a change
of parameter where others destroy the stability because they changed other
parameters within. Sometimes this can bring you to false conclusions. Pay
attention that you look at the right parameters and the formulas might get
simplified. Frohe Ostern!
