After playing with this a little more I have found the following behaviour.  If you put your pan speed down to +2 then it slows it down compared to 10.  I also unexpectantly found that negative pan values don't work well in the preview but the published tour is OK.

Example of +2 pan value:  View Tour  Click on one of the thumbnails to see the +2 speed, otherwise you will be viewing the movie speed.

Oh and if you see 4 white dots on the ceiling that is my camera slowly going bad not a flash problem.
