I don’t start the count down on a squish once I hit 1000 psi ! I’ve been going to 4000 psi slowly till it stop bubbling. Last squish was a rock hard bud of 8 grams and didn’t weigh the rosin . Mama finished it in a day and half ,maybe less .
There are a lot of opinions, but I haven't seen anything backed up with lab results yet.
