Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

While some would try to make rocket science out of seat height, that isn't necessary. Higher, short of having you reach for the pedals is generally better. It's sort of like playing blackjack, closer to 21 is better, but passing it is a bust.

Likewise, look for the highest comfortable seat height, and ideally have a friend confirm by riding behind you. Rocking hips as you pedal is an indicator that you've reached too high.

As for finding a happy medium between too low at the top of the stroke, and too high at the bottom, here short people are at a decided disadvantage since the typical 340mm pedal diameter is a greater proportion of their leg length than it is for taller, or longer legged folks. That's why they make childrens' bicycles with shorter cranks, and in reality many women (or short men) would benefit from this option.
