PADI Divemaster and Instructor course study aid. There are a surprisingly high number of questions in the exams on this topic.

Well done. 👍 Thank you.

I have always learned no more than 33ft/9m per minute on ascent

[@alexfinn7989]

Very well done 👍. If you get your tanks filled at altitude, would there be any difference in N2 and O2 ratios? Or is it still the same (just partial pressures are reduced), once tank is pressurized to 200bar it ends up the same. Thank you.

Same, the percentages stay the same and thus it obey's Daltons Law. The Compressor just has to work harder as the external pressure is less.
