The triple octave/double octave and fifth comparison is only for when I wan the absolute maximum and justifiable amount. Once I get into the last part of the 7th octave, all bets are off. But let's take a piano that is 1/2 step flat in the midrange. That's 100%. Very often, such a piano is not evenly low in pitch. The high treble may easily be 150% flat. Now add 30 cents for the high treble for the usual amount of stretch. We're up to 180% now, which theoretically would take +60 cents overpull. Yipes! Maybe on a new or newly strung piano but even then, I'd prefer to work my way up. The danger of breaking a string or splitting the bridge on the poor old Betsy Ross is simply too great. Add to that the kind of test blows needed to settle such a change and you'd be bustin' those elbows or breaking the keys themselves at the balance rail. It all adds up to a claim that I would really like to see substantiated: a 100% pitch raise in 2 passes that comes out "dead on". I'm not from Missouri but *show me* anyway.
