The 20-30 shave breakthrough idea must be pretty accurate too. I am starting to feel way less clumsy with the razor, am switching grips and hands often during the shave and don't need to think about it much.
My shaves are pretty much irritation free at this stage. The crevasse area of my neck still gets some minor irritation because I still have not figured out how to get in there effectively. And, my chin has some signs of burn because it tends to get the most attention/strokes in the shave. As far as closeness goes, I am still not at the same level that I am used to with a DE. Then again who knows, maybe I am at the same level of closeness that I was at with DEs when I was only a few shaves in with them.
