Personally, I think standover height has nothing to do with bike fit. Look at it this way ... you probably stand with the bike between your legs 1% of the time. So why use that measurement as a benchmark for fit? 99% of my interest is focused on how the bike fits while riding.
Do I feel stretched out, bunched up, seat can't adjust low/high enough. Handlebars can't adjust low/high enough etc...
This thought process may come from my experience riding motorcycles. I'm only 5'6". If I used my inseam to match seat height - I'd never fit/ride any sportbike! But since I only put my foot down when I stop - seat height has only 1% influence on my decision.
