in response to Alan's question about uneven string heights in Steinway and 
Yamaha:

I cannot imagine the design intent being anything other that equal string 
heights at the respective strike points.  Are you sure you were measuring 
precisely at the strike point?  
I don't know Yamahas that well, but every Steinway I have measured (hundreds) 
exhibits this. Typically, taking three measurements in the tenor, two in 
alto, two in treble, string heights on all models except the D would measure:
192mm-193-192 | 192-191 | 190-189 
or something like it. I've seen as high as 193-194-193 sloping to as low as 
188. I'd suspect undesirable plate warp, especially since the plate webbing 
usually somewhat mirrors this; but what do I know - I'm sure it's a Feature. Saw 
the tops off the treble hammers.
