I’m particular. I find that at or around 20-25K miles I adjust them. With the use of the Graves unit the “adjustment” is 1/8 of a turn or less.
The other brands have different pitch ‘screws’ and I can’t comment on those. Don’t use them-

Haven't done a valve check on my current '18 (MBD!) so still has stock CCT. On my previous '12, I installed a Graves unit at first check and didn't touch it until I flipped it for the too-good-to-pass-up '18. That was at ~42k total miles with ~18k on the Graves...still quiet. My '18 is close to check time so I'm pretty sure a Graves is in my future. The difference in noise (at least on my '12) was significant.
