you've tuned it a few times.  Whatever the case, I tend to push it toward
A-440 from either side in the hope it will stabilze a bit.  Some never do,
but at least you modulate the swings, which seems to help with over-all
tuning stability.  I never pick a note as an absolute, but rather pick a
pitch that seems to be average by a roughly equal number rolling flat &
sharp.  Location in the scale has a bearing on that judgement as well, since
some areas are inherently more unstable that others, or affect other areas
more significantly when pitch is changed.
