I dunno, everyone's facial seems to grow at different rates. I can only get 10-12 hrs before I feel there is enough stubble to warrant a shave. I rise early around 0500 and shave. Late afternoon I feel some stubble showing and sometimes do shave again. My stubble is never very long and the shaves are smooth. I can't see waiting 2 days and getting a smoother shave but have never tried it. I am thinking if the blade is up to snuff it should not matter. I am thinking it does not take much for the blade to be off a bit. OTH whatever works for the individual.
