One stone honing? It takes a bit of time assuming the finisher is not a man made stone, but you enjoy honing to the fullest; no hurry, you are taking your time and hone until it's shave ready. I enjoy it too.
What are you using? Coticule? Jnat with Asano nagura progression or just a tomonagura? If you do have a diamond plate, it does count, so it would be three stones. But slurry stones don't count. A successful method, and it does save you some money from the other one or two stones required, but not a good idea for people without experience.
