Records in piano

[John Ross]

Hi Jim,
I feel it is the humidity change. I have noticed differences, much more than
.3.
I have meant for years, to keep track of the numbers, re date, humidity and
amount off pitch. But I always forget.
If someone else, has done this, I would be interested in the results.
As to whether it would make a 'noticeable' difference to the tuning, is
another question, as different people have different tolerances.
