Great line !!!

Is the formula for SR which you gave me one your proprietary items
or has it been published yet?

Also, did you realize that on pianos which are not destined for/or not
worthy of  inertial weight balancing, that; by changing the FW by the
deviation to desired BW,  a uniform TW (touchweight) can be derived.
ie: 38fw/31bw to 43fw=36bw,(+5) or 38f/40b to 34f=36b (-4)

Of course SW, friction and leverage have to be delt with prior to this.
But this could be done as an alternative to assist springs, considering
of course the amount of lead already in the front of the keys.

And by the same token, by graduating the FW without the assistance
of wippen springs would make the BW irregular.
