The microgrand gets more play time. I would not be suprised to find that the Yamaha gets some harder play, but she is not a pounder by any measure. I would have to say that there is not a significant difference in the play factor between the two pianos. 

Thanks for your interest Carl. I used your wonderful key leveling system yesterday on an old upright. $550!

She also has a 1930ish Aeolian 4'some" microgrand in the same room. I have tuned both pianos several times at six month intervals. The Yamaha consistently goes out of tune significantly more quickly than the microgrand. No RH monitoring and no DC (on either piano). The Yamaha does have business card gaps between the pinblock and the flange.

She is going to start monitoring RH in the room. But keep in mind, the Yamaha goes much more quickly out of tune than the microgrand. Any other suggestions for things to look for? This is a significant problem for this piano owner. I need to solve it. Any input will be greatly appreciated.
