A fair point, but honestly I like Dave's idea.  What I'm building is in no way realistic, but it makes for fun gameplay!
Thanks for all the good feedback, nice to meet such a troll-free list!
[anyone wanna take a stab at a plugin for this option?]
      -For me on realism.  It depends on what I'm doing.  AS doesn't push
suspension of disbelief anymore than most science fiction novels do,
so I see no issues with the orbits calculated as is.  I'm also a
consistency fiend.  When my players say "Well that's not very
realistic" it's becuase something in my internal consistency is off.
Though they're more likely to assume that anything 'off' is part of a
plot device.  But even a fantasy world has rules of what is and isn't
possible... and has perceptions of what is and isn't possible.  And
it's the difference between the two that frequently allows you to
surprise your players.
