We don't put out enough power to have our saddles that high. Secondly, these formulas have no way of taking into account even just the thickness of the shoes we are wearing, let alone important factors like length of femur vs length of tibia, and foot length. Nor do they take into account where your saddle is in terms of fore-and-aft (or where the part of the saddle you actually sit on is in relation to the length of the saddle). Obviously, the farther back your sit bones are, the farther away you are actually going to be from the pedals. The formulas also don't know whether your foot is flat or pointed down at the bottom of the stroke. A pointed down foot adds a lot of length to your leg, doesn't it? So, in the end, as long as you don't have your saddle ridiculously low, like a child learning how to ride, you do what feels good for you. If you need some validation for this, you can take comfort in the fact that pro racers did not used to ride with their saddles as high as these formulas call for. For most people riding a road bike, a good saddle height would be anywhere between the high given by the x .883 formula, and the lower "limit" given by the heel on pedal method.
