Douglas - Nice try, but a smidge more rotation to the left please. 
Maybe 0.1 or 0.15 degrees.  Trust me on this.  I just finished 
squaring just over 900 scans of negative pages for my archives.  My 
eye is really tweaked for sub-degree tilts right now.  ;-)

With all the angles in the shot it needs to be tweaked by eye, not by 
measurement.  You want it to look level, not necessarily be level.

It's a tough one, for sure.  :-)
