Pitch Raising to A440.......Or Not?

[Don]

Hi David,

It is not the board(wood) but the plate that reacts instantly. That's why
individually tied unisons drop *less* than looped (shared hitch pins), and
why full perimeter metal plate pianos drop less than other designs.

I do agree that deliberate overshoot to a pitch level higher than A440 is
not necessaryily useful.
