I have to say, though, that maintaining the same blade gap while altering the exposure seems highly likely to have its drawbacks. Unless you ride the cap (which I never do, since it negates the whole point of a safety razor design) the implication is that you would have to tailor your shaving angle to every setting if you don't want to risk flaying yourself.
The gap changes along with the exposure: ( see gif about half way down)
