Just got all my shaving goodies, and I've noticed that I can rotate the bottom setting knob 2 or 3 times all the way around. Which rotation is the right one (given a suggestion to start at a setting of 2 or 2.5 for the first month)?
After opening it up and sticking the blade in, the base catches the top plate at 4 or 4.5
4.5-->3.5 Spring offers resistance to top plate
5-->1 gets tighter
Gets even tighter, not sure if the blade will actually touch the skin at the lower numbers during this rotation.
