Actually, David, I find the opposite to be true for me. I find shaving a few days' growth to be more enjoyable than shaving that of just one day. The resistance, or lack of it, is the same regardless of the number of days' growth but for some reason the shave is more pleasant. I suspect that part of it is the visual feedback of seeing the removal of a lot more whiskers. Primarily, though, I believe that it is because after a longer rest the skin more fully has recovered from minor abrasion damage than it does after a single day.
