Hi Ron, Next time I make the experiment I will tap coils and bridge pings etc. I don't have a lot of data on this--but I have seen a pitch change of up to 4 cents *higher* 30 mins after a tuning. In the particular case I did stay and worked on their computer cleaning it up and 1.5 hours post tuning the pitch was back down to A440.
