FWIW, my progression is as follows:
Sharpening: Chosera 400, 800, 2k, 5k, 10k, then 1m, .5m, .25m diamond on leather or balsa, depending upon my mood. Lately I am preferring the balsa, since I believe it to have less give.
For touch up, usually start with either the Chosera 2k or 5k and go up.
Reprofiling: add the Atoma 140 first, then stock EP stones until I'm happy, then back to the Choseras. I will intermix a 220 or 320 DMT in there as needed.
German knives, etc.: stock EP stones, up to 1000, then maybe .5 CrOx, depending on the steel.
Maintenance: I have a 3x8 strop charged with 1m diamond that I keep in the kitchen.
This is working very well for me right now, but it's subject to change without notice, particularly if I want a new stone to play with...............
