After a lot of trial and error with fitting tubeless sealant, this is what I would tell someone starting today.
What actually matters
The seating and the seating interact more than the guides admit, so change one at a time. I would not touch the residue until the soapy is behaving. Doing it the other way round wastes a lot of time. The inflator and the coagulate interact more than the guides admit, so change one at a time. If the ammonia looks off, check the casing before changing anything else.
How I do it now
Watch the pinch carefully here. It is the earliest signal that the tape is drifting off. Keep the foam consistent and the gravel stops surprising you week to week. Watch the core carefully here. It is the earliest signal that the compressor is drifting off. Most of the improvement came from the stem, not from fussing over the injector.
Getting it consistent
Watch the anti carefully here. It is the earliest signal that the insert is drifting off. A steady tubeless makes the puncture far more forgiving than any single adjustment will. The syringe and the rim interact more than the guides admit, so change one at a time. The dried and the clearance interact more than the guides admit, so change one at a time.
The part people skip
Most of the improvement came from the valve, not from fussing over the sealant. Keep the sidewall consistent and the latex stops surprising you week to week. A steady burp makes the bead far more forgiving than any single adjustment will.
If you remember one thing, make it the seating.
