Longer Rounds?

[BaneOfGiygas]

I work on the method of "Does anybody object to a shuttle call?". Wait a handful of seconds. If nobody objects, call it. You have five minutes to recall the shuttle, after all, and if you can't get to a console by then (or convince someone else to), then...

This is usually what works the best, in my experience. Also, as the wiki page for the AI says, if recalling the shuttle is rendered physically impossible due to major station destruction and/or loss of other people capable of getting to a communications console, it was probably worth calling anyways.
