Jane and Molly have similar arm, torso and leg lengths (not to mention two very nice derrieres). So duplicating Jane's bike geometry to Molly's was a no brainer - the perfect starting point. We'll ride this weekend; I'll let you know how she likes it. Thanks; I think we agree on most things. :-)
"Standardized fit dimensions" are, at best, a starting point for individuals. Some riders are quite tolerant of a variety of bike positions and others very particular. You may have to make adjustments.
BTW, Greg LeMond's fitting method was based largely on him and he had unusual proportions in that his femurs were longer than most people relative to his leg length and overall height. His frames had shallow seat tube angles that didn't work for most riders. So, be aware that a "standardized fitting method" may not be standardized for you.
