As I am sure you are aware Japanese knives are made with several styles of bevel. Single bevel, Western double bevel and a double bevel with each side at a unique angle. They may also come with smaller bevel angle than many western knives. Being left handed I have stuck with western style double bevel with my Japanese knives. Also try and develop a light touch with the diamond wheel as it cuts quicker than the SG-250. I also like to use a jeweler's loupe to inspect the entire knife edge. You will often find areas that were missed in your initial passes due to prior poor sharpening practices.
I maintain a small concierge sharpening business with limited customers as I don't want it to turn into a job. One thing I have done is create a notebook with a section for each customers knives. I include sharpening angle, jig projection length for next time and any reprofiling or repair that I need to do.
