Data Driven Fret Process.
Please keep in mind, I use a CNC to machine the neck, the conical radius fretboard and the fret slots. I don't require a full fret level. My frets after installation are already level to each other. My "high" spots are actually not that high. They are microns high. I'm not taking off much material. This method is no different that spot leveling an already leveled board.

I also do a final check with the rocker during the polishing stage. If I detect any tiny rocking, I remove it with the Dremel and cutting polish. That is how tiny the "high" spots are, they can be removed with polishing compound.

Color high frets Red, color nonhigh frets black.
Step 1. Spot level the red frets.
Step 2. Recheck with the rocker on the adjacent frets. The black frets are either low or correct. Adjust the AsIs color coding and spot level the black frets if necessary.
Step 3. Continue down the board spot leveling.
Step 4. Crown only the portions that were spot leveled.
Step 5. Recheck with the rocker
Step 6. Polish with Dremel. Remove any minor rocking with the Dremel.
Step 7 Liquid polish.
