>>Since felt compression also takes place on the balance rail punching,

>>and thus reducing the dip, I don't think that makes much sense.

>>One of the local techs here in long island, during a presentation detailing
>>his key height/key dip setting procedure, said he likes to set the dip on
>>the piano in something of a bell a curve, being slightly deeper at the ends
>>and slightly shallower in the middle.  This, he said, was to compensate for
>>the gradual felt compression which will occur during playing, since the
>>middle gets more wear than the ends.

>>Just another idea for the mix.
