W/O Seeming too pretentious...
I do fits out of Roy's Sheepshead Cycle in Brooklyn. It's the BG Fit method as designed by Andy Pruitt. I charge $250 on a road fit. It takes how long it takes. 2-4 hours is the usual range depending on the bike and the athlete. Tri fits can take a bit longer due to the number of parts needing adjustments...
As far as fittings go, it's a complete top-to-bottom fit. Cleats and all. Being a knee-pain sufferer for 10 years, legs and feet seem to be my strong point on the fits.
There's no smoke or mirrors. It's a straight up bike fit that measures the body, its limitations and adjusts the bike to work with the given specifications.
