I don't really know a lot about speeds on a stone, only 2 years into this honing experience. I have finished about 6 razors on it now. Coming from an 8k, I get a beautiful shave at about 35 strokes. I have touched up 2 razors with 10 to 12 strokes, to get back in the game.
Compared to my PHIG, it's like the Concorde was from New York to London.
