Most places the routine interval between tunings IS six months. In six months, which would include at least one - if not two - seasonal weather changes, pianos will be whiningly out of tune regardless of pitch raise. After a year they will often need another pitch raise... At least that's how it was in Boston. Here in Northern California (where Dave - and now also I - live) - it's Piano Paradise. Typically, humidity just doesn't change much over the year. So our idea of how long we can get away with letting a piano sit without tuning is somewhat distorted... If you want to deal with the "settling" of a piano after a pitch raise in the usual, four-seasons-a-year type climate (that is, all of the Northeast, Mid-Atlantic and the Midwest) before the seasonal weather change makes it irrelevant, it should be done a lot sooner that six months - and definitely sooner than one year.
