Having gone a few dives with the Shearwater, I'm still observing my SurfGF with interest.
I'm running 45/95 and on the 1st dive over the weekend with a max depth of 91ft, I got to within 3 mins NDL and started slowly ascending waiting on my buddy. When I reached 50ft about 7 mins later I was now showing NDL 22mins however my SurfGF was still at 95. Interesting. NDL really gives you no idea of how close you are in terms of deco stress. Before having the ability to see SurfGF I would have thought I was very safe and could stay deeper longer air provided which I usually have. My dive buddy was a very experienced lady, so she had pleanty of air too, but 2 others did not, so the dive was just 38 mins.
Continued my normal slow ascent with a 5 mins safety stop recommended (adaptive mode), but I stayed just a little longer and ended with a surfacing GF of 66.
