LPR: 70 ish
HPR: 170 ish
Of course there might be numbers that work better on other markers (as each marker is a little different) but these are the numbers I've found working the best so far.
My numbers are right around there, but mine are a tad bit lower, Im going to presume mines just a small bit more broken in, or it just likes the lower pressure
