Tom, I couple of questions in response to your problem.  Are you tuning the 
piano to standard, or leveling it off at 438?  When you say that the all the 
notes were being lowered starting with about -1.38c, are you talking about 
starting with A0?  Which pitch raise (lowering) mode did you use; +3%, 
standard, -3%, etc.

If you are tuning to standard your problem doesn't make as much sense unless 
you have experimented/changed the octave stretch setting.  If you are used 
to, say, tuning to the RPT setting, and went to a wider octave stretch, then 
you would be lowering notes almost into the temperament area.   In the higher 
treble areas you would see just the inverse.  -1.38c is not a lot of lowering 
on a note.  It's possible with it being summer and all -high humidity in some 
areas, that some notes have gone slightly sharp.  Remember that the note that 
you are tuning is it's cents deviation, averaged with the 6 notes before it.  
This is done to assure smooth transitions being intervals.
