If I'm interpreting you correctly, a mandatory safety stop isn't a
safety stop so much as 3 minutes of planned deco.  This is beyond the
limits of recreational (no stop) diving.

It's worth noting that dive tables and many recreational dive
computers do not use gradient factors or other ways of adding
conservatism.  Some users may want to run 100/100 gradient factor for
recreational dive planning to be close to the tables used in courses,
or a basic dive computer planner.  The conservatism comes from adding
in a safety stop, and ascending several minutes before the NDL reaches
zero.

I'm not suggesting another check box for automatically using 100/100
GF on recreational dive planning, but perhaps it's something that
could be mentioned in the manual or FAQ - "How come the Subsurface
recreational dive planner is so much more conservative than my dive
tables?"
