Having spent the last two days tuning mostly Yamaha P22s at around 25%RH, from 70%+ RH just a few months ago, I have a request. Has anyone out there ever taken complete scale data on a P22 that they would be willing to send me? I'm curious how tension and break% profiles correspond to the pitch change patterns I see in these pianos, and I haven't yet had occasion or opportunity to take the measurements. Looking for data to compare to observed reaction, for educational purposes. Ron N
