Also depends on altitude.

  I read something along the lines of +5% cook time for every 1,000 ft above 2,000 ft. Apparently it's adjustable in their Ultra model: https://instantpot.com/portfolio-item/ultra-2/#toggle-id-15 https://instantpot.com/portfolio-item/ultra-2/#toggle-id-15

  Why would it depend on the altitude? It's a sealed vessel that holds (iirc) 7 psi on low, and 11 psi on high. It seems like these pressures should remain the same regardless of altitude, unless the outside atmosphere is somehow involved in the pressure release valve, which is hard to imagine.

    Traditional pressure cookers with weighted regulators would need different weights for different altitudes for consistent cook times. The sensors/mechanics of the InstantPot are a black box to me, so I'll just have to assume that it makes some kind of difference since they added an altitude setting to one of the models.
