At what % does sh stabilize at?

I thought that I remember reading somewhere that sh starts to stabilize at around 6% but I cant seem to find anything that supports my “memory”

Anyone know anything about this?

If collective memory counts for anything, I’m with you. The difficulty that you find when using 6% that started at 12% is that you still have all of the salt but only a small portion of the original power.

Where my thought process is leading me is that when I buy my sh, if I cut it immediately, would it stay more stable and keep longer?

Out of my league.
