Hello Ray,

what could these numbers tell us?

I still need to compute the balance of the forces; can the front mass "leverage" due to the greater fall significantly counteract the seat rise force? They act against each other and the result will depend on weight and leverage - I'm not sure what the lever arm is, at the moment.

I'm also not sure if the methodology is generally true, maybe Dirk can help. His matrix math is a bit more complex.

Dirk once said that there exists a specific angle for
every frame geometry where the pivot rise is maximal.

Which data does one need to calculate this angle and
how is it done?

I remember reading that, I think I just need to iterate over the ranges of the input space.

Lots of questions ... 

Yes, I'm procrastinating cutting up and welding for now.

PS: If are working on a config file for your program, could
you please include flags for metric/imperial and maybe the
possibility of changing the limiting values for the sliders.

I'll make a config file, but saving one from the current state is common but a lot of code; it will have to be edited manually for now.

Ray
