I have this strong urge Richard, ma bud.....
That's why I react right now.

I personally have come to the conclusion that there is actually just one key
dip and that key dip is 10 mm sharp, and no more than 10 mm.
All piano makers in the world have a key dip of 10 mm except the earlier
Pleyels, Blüthners and modern Steinways.... although, when I had my lessons
at Steinway the head technician at the regulation department told me that he
thought a key dip of less than 10 mm on any Steinway was bloody baloney.

I base my opinion on 30 years of regulation with special thanks to the
Yamaha corporatation.
I have never ever encountered so much precision and discipline as in the
Yamaha factory. It would be very very good for the techs at Steinway if they
could only follow the 'basic grand piano course' in Hamamatsu, if only to
learn again what discipline and perfection is all about.
In regard to making key dip : I had to train one whole week to learn what a
perfect key dip is.
After that, when I read about various key dips, I always feel this urge to
open up the magic box and type in the words I just type in.

Most elevated and friendly greetings.....
