Hey there jerry
Personally, I don't think you need to play the fig shuffle in the Fall. Keep your figs out until the leaves drop, even if there is an overnight frost or two. There's no way a slight frost will kill your plant (IMHO). That said, once it's cold day and night haul your fig in, wrap it up, do whatever u need to do to keep it from freezing temps and wind damage. I just don't think a few extra days if in/ out really accomplishes anything. Leaves drop, bring in and put to bed.
Now in the spring! thats a different story.!
