Anyone got any comments, good or bad on this stab at a run-time plan ??

Diving on a vision so auto switch from 0.7 to 1.1 on the way down, then a manual switch up to 1.25 at first deep stop and probs ramp up to 1.5 for the 9 and 6m stops

Surface (137) Diluent 9/72 -9m/min ascent.
Off gassing starts at 89.3m
OTU's this dive: 188
CNS Total: 68.9%


Just a followup thought - CNS and OTUs are quite high, so would anyone do another shallow (<20m) dive after a 2/3hr surface interval ?

flack jacket mode on

cheers

I would not run 1,5 at 9m. Save it for 6m and shallower. And I would bnot be divign the same day again Did not notice at first that you intend to change from 1,1 to 1,25 ppO2. I would keep running 1,1 until 6m.

I personally wouldnt bother setpoint switching on the way down.

Id run manual 1.5 as much as possible @6m

Yur descent speed looks slow - currents?

whats OTU and CNS?


I'd worry more about DCI for 2nd dive and wouldnt do one
