I'm dumb for even typing to a sock puppet...

V-Planner is just a nice GUI for the VPM model. It may even have errors. Even if it's coded perfect, VPM is just another MODEL. There are at least a dozen of them. None are considered a 100% accurate representation of what dissolved gas and bubbles are doing in the body.

Your best shot is to find a good test group that has done lots of dives like the one that you're contemplating. Ensure that they've had a relatively low incidence of DCS. Follow their protocols. Hope that your body behaves similar to theirs.

Study up on the concept of a model. Here's some good info on the math behind some of the more popular models.


This is what you'll find at the bottom of any V-Planner generated table.

********* WARNING & DISCLAIMER *********
This V-Planner generated dive schedule could indirectly kill you.
The author does not warrant that it accurately reflects the Varying
Permeability Model algorithms, that it won't get you bent or dead, or that it
will produce safe, reliable results. This dive schedule is experimental
and you use it at your own risk. Diving in general is fraught with
risk, and decompression diving adds significantly more risk.
Deep diving utilizing multiple gasses, including Helium, is about
as risky as it gets.

This schedule is not intended for uneducated users. V-Planner and the
decompression schedules it produces are tools for experienced mixed-gas
decompression divers ONLY. If you have not been properly trained in
mixed-gas decompression diving by an internationally recognized
technical certification agency and/or don't have a firm handle on decompression
planning and mixed-gas diving, then DO NOT USE THIS DIVE SCHEDULE.
