Regulating Upright Pianos
By Larry Lobel

Referring to the Piano Action Handbook of the Piano Technicians, Guild,
which lists action measurements for dozens of brands (though not the
Lindemann), the range for hammer stroke is from 1 3/4" to 1 7/8".
There are no pianos with a stroke of 2", and that would be too much.
The let-off is almost universally 1/8" for upright pianos.

Before changing the regulation, I would check the action bolts and
brackets, and the height of the keyframe, to make sure there hasn't
been some change to account for the excessive hammer blow distance.
