If you look at how the plan looks like when it is initialised with the
box unchecked,
the first line represents your descent and that is the one that gets
discarded when you check the box.
Maybe we need to clarify this in the manual a bit more
The way the “Drop to first depth” is designed is that it takes the
data from line 2 and assumes that you drop like a stone to that depth.
* If you intend to use the “Drop to first depth” it should be checked
before you start adding waypoints to your plan.
This is only useful if you are diving from a boat or a place with deep
water close to shore.
If you start your dive from shore the box should be unchecked.
Otherwise subsurface can’t do proper calculations for your long and
shallow descent.
* Each line in the planner table is the position of a waypoint and
represents the end of a segment.
That is an important distinction originally lost on me.
Another thing you can do is to check the box for “Verbatim dive plan”.
Then there will be a description of you dive in plain text.
For your example dive it looks like this:
Transition to 130 ft in 1:58 min - runtime 1:58 on EAN26
Stay at 130 ft for 5:02 min - runtime 7:00 on EAN26
Transition to 70 ft in 2:00 min - runtime 9:00 on EAN26
Stay at 70 ft for 10:00 min - runtime 19:00 on EAN26
Transition to 0 ft in 4:09 min - runtime 23:09 on EAN26
I was noticing that in the box to the right. Looks nice and helps
clarify what is happening.
If you let the planner know which cylinder you are intending to use as
well as your SAC
(which subsurface can calculate for you if you add the cylinder size,
start and end pressures of the dives that you import)
you get this little treat at the bottom of the Dive plan details.
Assuming AL80.

Oh, and option to pick between 15 or 20'. I noticed only 20' was
set as the last stop.
That is because the planner used 10’ increments in its internal
calculations.
And the planner will only calculate what reamins on the ascent
after your last waypoint.
OK. How about another check box to "include 3 min safety stop at
15 feet" at the end of the dive. At least that is what is being
taught in PADI.
That might not be to hard to implement.
I'm still interested in that option.
Thanks
