Why? I still need a strictly aural "as refined as possible" tuning that 
the master tuning would supply.

I don't think it matters at this point. For now, we need some sort of 
trial to define the questions.

I don't think it's critical. The point is to do the same thing to the 
piano at different RH% levels and compare results.

I don't see that it matters.

No, if you're going to try to fake the data, count me out. The whole 
point is a sampling of real world results. This is exactly why I do my 
own research when I can, and why I haven't brought this up until now, as 
I've wondered about this for some years. If we can't do it right, let's 
just not do it at all.
