For pressures above atmospheric, and reasonably big gaps (say, bigger than a
few mm), breakdown voltage is going to be proportional to absolute
pressure... that is, at 15 psig, the breakdown will be twice that of
atmospheric (i.e. it will be 140 kV/inch instead of 70 kV/inch).  at 150
psig (i.e. 11 Atm), it will be 770 kV/inch..

At lower than atmospheric pressures, it stays fairly linear down to around
10-30 torr, at which point it starts to get funky.
