    Elevation decreases atmospheric pressure, and the difference is pretty small in the ranges that people actually live.

    A pressure cooker increases pressure by about 15 psi above atmospheric pressure which is pretty huge, nobody lives 5km below sea level (although it’s more complicated than this).

    So yes, pressure cookers do cook things faster, but the pressure difference altitude makes is basically irrelevant

      That’s not entirely true actually. At 1.5km (≈5000ft) altitude it’s roughly a 5°C (≈9°F) difference which might not sound a lot but depending on the dish that can double the cooking time. 1.5km is a relatively high altitude of course but not unheard of for villages, smaller cities and also Denver.
