I shaved with my new Progress this morning. I think I had the notches misaligned, as when I tightened it down, it was on # 3. After shaving I ensured the notches were aligned and after tightening I seen the # was 5, so a slight adjustment brought it to 1. I had a decent shave on 2 but it felt rather aggressive. I'll try it on 2 with the head on the right way next time.
