You start checking the centerpins on your out of the box flanges and you may
come to the same conclusion yourself. I repin as I am insterested in
consistancy, and making sure that the pins are not too loose and not to tight. I
use the swing test and  the tap test on grands, and the tap test otherwise.

These are done after I make sure that the pin is just as tight in both bushings.
If you got one side loose and the other side tight... you are asking for trouble
later on. ..grin.. and there is always plenty enough of that anyways so why ask
for more ?

Never checked exactly how much grams of friction.. I do this by feel. As for the
rest of your questions about how often do you rechange... I change them as
necessary... within the limits of my service time. I sell 90 minute service
calls... not tunings... so I generally have plenty time to do some basic
maintenance.
