The aforementioned referenced .883 - (as well, .885) Guimard ("LeMond") calibration, while not absolute, is still the best baseline calibration based on classic physiology set up...... Inseam times .883 - or .885 equating out to a baseline that measures from center of bottom bracket to center of saddle height running parallel to seat tube. Once you employ this formula you are typically within a mm or two or more to realizing the most efficient saddle height to that of the center of the bottom bracket. Your choice of crank arm length should typically fall right in line with final adjustment but only a few millimeters as per your preference of final adjustment. You'll arrive at what is most suitable for you and you will again find that the .883/.885 percentage of inseam is your best formula.
I more than fully agree with NOGLIDER's thankful remark of having a slight (2 to 3 degree) saddle pitch up (based on a straight line as "level" running the entire length of the saddle and tilting the saddle accordingly)....., never tilted down which is the new age (read: dumb) thing.
