[pianotech] How come?

[Bppiano]

Curious, what type of enviroment is your part of the country?

After years and years of questioning my hammer technique, I've found that using a smooth pull up to the pitch while using FF blows every second or so gives me very reliable pitch consistency.  Of course to actually hear the note, I play very softly.  Once I think I have it, I then go through several test blows maybe not quite as hard as before to test for stability.  Of course, there is a tendency to break strings but what do you want-- confidence in stability or not?

I'd be interested to hear what Mr Nossman says about this.  Could the soundboard be settling a little every year? Those notes are obviously near the edge of the board near the inner rim, could the give (losing crown) in a soundboard occur first near the rim?

I have quite a few customers that I tune once a year, like clockwork. The pianos are very stable, often off by less than one or two cents, all up and down the keyboard, xxcept for the top four or five notes. Invariably, these notes are low as much as 6 cents. When I first came here, I noticed that most pianos were a little flat in the top octave, and assumed the previous tuner just didn't get it right. But now I'm having the same syndrome. 
 
Recognizing that the middle of the soundboard fluctuates the most, and presumably the edges of the soundboard don't fluctuate at all, how come the last 5 or 6 notes in the high treble are going flat?
