So you say! Evidently you don't think if not written cubits, palms and digits in unit fractions you might not realize the full the intent and reasoning of the Ancient Egyptians? If you miss the reason for chosen dimensions for each pyramid, each chamber, etc. then the whole exercise would seem to be meaningless. Since you wish to use the pixie stick (chance and whim) method of design I do wish you good luck on your endeavor.
