[pianotech] Damper Lever Resistance

Those of you who use gram resistance gauges to set damper lever spring
tension I'm curious what guidelines you use in terms of the number of grams
targeted but more importantly, perhaps, where in the damper lever stroke do
you target: with the damper at rest, at half blow, at the top of the stroke.
My own goals with respect to this are to achieve effective damping with the
least possible difference in touch perception between playing with the pedal
engaged and not engaged.  I don't like to feel that the dampers are playing
much, if any, role in the touchweight dynamics.  But I've not really been
able to pin a number on it exactly.   I know when it's right but sometimes
find myself going back and making corrections.  Renner publishes a guideline
with their damper tray kits but I tend to find those settings too high
sometimes depending on where in the stroke you use them.  So, input is
welcome.
