I find I do get a smoother shave when I skip a day inbetween shaves but I believe it has more to do with the skin having plenty of time to heal than it does with the length of hair.

If I take my time and concentrate on the shave (watch the pressure and angle) I can shave just about every day without anything more than minor irritation. If I do mess up then I just skip a day or two and then I'm back in the groove again.

Keep at it and always remember that the goal is a comfortable shave.
