Well, today I think of Occam's Razor in the spirit in which it was originally offered, according to one translation, "One should not needlessly multiply entities."

Not only is it a great answer to the original question ("How many angels can dance on the head of a pin") but it is a great engineering principle as well.

So I agree with the GP who says that use of two competing variables which differ only by a factor of two is redundant and runs up against this principle.
