user manual: pSCR diving is similar to OC, not CCR
See also commit acb38c9e00f2. pSCR is with respect to cylinder planning very
similar to OC planning. Obviously, the SAC is much (max. 8x for counterlung
ration 1:10) lower, but multiple gasses are common (in all but recreational
pSCR diving).
Changed the wording to reflect this.

The dive is comparable to that of the CCR dive below, but note the longer ascent duration due to the lower oxygen in the loop due to the oxygen drop across the mouthpiece of the pSCR equipment. |
