BSL, how would you structure such at experiment, or model? Probably better to look at factoring strength rather than muscle mass? or try to estimate the efficiency of a large muscle rather than a small muscle?
I find a longer lever (recently switched up from 170s to 172.5s) feels more efficient, but after a while my knees don't like the extra pressure. I'm better off spinning.
