Yes, I noticed the same.  It's completely wrong for vpm.  To get it to
work, we need to calculate Buhlmann "percentage" values, which isn't done
for vpm at the moment.  Adding it shouldn't be too difficult.

For interest's sake, you can create a vpm plan, save it, go back to the
planner to set the deco mode back to Buhlmann, then close the planner and
view the saved vpm dive....

Another oddity I noticed were the plans used in the navy study in the
presentation.  Both the non-deep stop and deep stop plans were for 30min at
170' (52m), for a total dive time of ~210min all on air. First stop on the
non-deep plan was at 40' (12m). To approximate that plan, I needed to set
gf to something like 150/60.  Very wierd plan.
