The shave is the real test of any honing effort. The number of laps on the 1200 and the blue really depends on the condition of the edge when you begin and the steel. It will very a lot.
The rest of the laps seem to be on the conservative side. It is not unusual for me to use 100 laps on the Chinese 12K after the Norton 8K. But... I also never mix the coticule and the 12k.
15 laps on the 0.5 chrome Ox is minimal. My numbers are 20-50 depending ....
The good point is that your approaching this in a conservative fashion. Good work and keep experimenting!
