Unfortunately the villages does alot in trial and error.
Well we added a 2nd one in place of a can lite next to it and ran a separate duct to the soffit and put in draft back flow dampers in the soffits that the villages missed and is a direct must under Nutone standards.
The 2nd fan is paralleled in electrically with the first fan and is on a 15 to 1 hr selectable wall timer.
It solved all are humidity problems and foging of the mirrors.
Good luck folks.

Very true. The bathroom exhaust fans are woefully inadequate for our larger master bathrooms. I added a timer switch to mine, and let them run an additional 10-15 minutes when we are done.
