What part of "assuming a flat ground" is not getting across? :)
If you are willing to assume a flat ground, then you already *have* a
valid and workable model that requires no modifications whatsoever.
Don't bother with the per-gear stuff, you neither need it nor want it.
If, like me with my ski jump fancy, you want to be able to deal with
ground that isn't flat, then that assumption goes out the window and
you can *not* assume pure Z compression. If you don't, don't. But
don't do it half way, it won't do anyone any good. If you don't
believe me, try this: what specific circumstance would be helped by
your hybrid per-gear force computation, and what would the
quantitative difference be?
