temp change=how much pitch change?

[pianolover 88]

Simple. If all concert pianos had full DC systems installed, the pitch 
wouldn't change to any substantial degree, providing that the piano is 
stabilized first, with regular tunings. The RH fluctuations will obviously 
cause swings in pitch as the soundboard takes on/lets off moisture. DC 
systems take this problem out of the equation. At least in my experience.
