I agree that rules of thumb are only starting points. The heel-on-pedal at max leg extension puts my saddle a good 3 cm too low as I like a lot of leg extension and tend to pedal toe-down. But it's a good starting point.
And get your saddle set back to where it is comfortable before doing anything else; IMO and IME, saddle height and setback are the 2 primary adjustments around which all others are determined. But heck, if you've been comfortable with your previous "4-inches-too-low" and slammed back saddle -- no hip-rockin', no aching quads, no strained whatever it is along the inside of the thigh, you have been doing it right. But I disagree that standover is a negligible part of fit; try an emergency dismount on a steep slope facing uphill.
