what would that mean for the planner? Except for recreational
mode, the planner always starts the ascent at the end of the
manually entered waypoints. Would you want to say something
like “go to 80m and then figure out the pressure at which you
have to leave 80m so you and your buddy make it to the surface
with x bars remaining”?</div>

Robert,<br>
<br>
Correct. <br>
<br>
Of course, actually, I commonly dive 230 bar and start the ascent at
around 90-95 bar, using thirds. So the 77 bars accurately
constituting a third is really a bare minimum and it is affected by
deco obligations. But a message indicating "Ascent back gas
pressure = 90 bar, i.e. within rule-of-thirds pressure (77 bar)"
would be helpful. It is an additional bit of safety information that
checks the accuracy of the deep section of the overall dive planning
outside of Subsurface. Does this make any sense?<br>
Kind regards,<br>
