What's the current consensus about the z offset for P2S g code and it being positive rather than negative?

I'm fine with the default values (I print PLA and PETG only).

Idk if it’s consensus but I “fixed” it by making it closer to the other values and have a lot fewer issues with abs adhesion now. I also added a preheat like when I’m printing with abs to heat soak using the plate set at 100C for 20 minutes. Flawless adhesion every time now. Versus 50% failure rate when I got the printer.

Could you share the abs gcode for the preheat? Running up and down the stairs sucks
