I agree. That's why whenever I can, I open the lid of the piano or harpsichord
or whatever I'm tuning (at the university) a good while before I tune it!
Thankfully, our conditions are fairly stable.

But I've tuned in other conditions where the piano changes while I'm tuning
after I've opened the lid. :-(
