I concur entirely Ed, tho I have heard the opposite said. In essence doing this
means the jack tender engages the jack before the letoff button touches the
whippen, and that seems to be a point of contention for some.. But it makes more
sense to me in anycase to do exactly this, at least to a very small degree even
if the piano is "perfect". Doing this smooths out that aftertouch bump without
making it spongy.
