Renner "Turbo Wippens"

"Although 45 and 36 are fairly close,  the point is that the spread
between DW
and UW is most certainly not all due to friction"

It can only be friction because you are not considering speed or
acceleration, which then would bring into play momentum and inertia. The
amount of effort to set a mass in motion is very tiny compared to the
forces? of friction that resists the points of motion in a piano action.  
IMHO  Also the question has to be asked, what if there were no friction ,
what would be the difference between Dw and Uw.  You couldn't measure it,
otherwise balance scales wouldn 't work.
