Re-Evaluating My GF

[Stoo]

Who else checked out this thread thinking GF= Girlfriend?

Yup. I was kinda hoping for pics tbh.

GF 50/80 Produces:

• 170 FSW for 30 minutes
• 70' first stop
• 134 minute run time, air decompression

Hmmmm; when I run it the way the OP describes it in Multi-Deco, using ZHL-16C with GF 50/80, I get a run time of 168 minutes.....trying compare ascent rates and other configurations between subsurface and multi-deco now.....

I must be missing something in the setup. When I run it in Subsurface I get 170 minutes runtime.

I very well may have screwed it up as well.

This is almost as good as actually diving.

I haven't updated to the latest version of Subsurface yet, will do that after this post and run it again:

Subsurface (4.8.4.0) dive plan created on 2/15/19
Runtime: 170min, Stop times: + 1:55 /ft + 7:10 /min





CNS: 19%
OTU: 53

If it makes that big of a difference, there is something really wrong with the tool. It typically matches my Shearwater pretty close though. My ascent rates are all set to 30 ft/min. Descent is 60 ft/min. Salt water.

Well......I relearned something very important. When I have the last stop set at 20', which I routinely use in planning Jupiter/West Palm in the wintertime, I get the ~170 run times. When I "uncheck" that last-stop-at-20' box, I get the 134 minute run time. In multi-deco, similar effect, from ~168 to ~128. So, disregard my post starting with ….hmmm and all that followed from me; I was entering the planners with a last stop at 20', and on air decom on this profile.....that made all the difference.
