"Having the drop set too low will create a larger zone before let-off where 
the pianist must play against repetition spring resistance."

This statement is so straight forward, everyone should know that.

I didn't. I had never thought of it. Makes perfect sense, and I can easily understand how the pianist would feel that on soft playing. Thank you Ed. Thank you, thank you, thank you, thank you, thank you!

This list stuff is great.  :-)

Stéphane Collin asks:

    The jack is in contact with the knuckle from the bottom of the hammer 
blow to the point of let-off,(and even then, the distal side of the jack may 
lay against the proximal side of the knuckle, but that is not usually a 
factor in the feel).  
    After the drop button contacts the balancier, the jack has sole support 
of the knuckle.  On a hard blow, this is not felt, on the softest, you may 
find that the later the drop screw engages, the less friction there is upon 
let-off because the balancier is holding up part of the weight while the jack 
is pulled out from under the knuckle,  ( on many actions, you can actually 
play a note very softly with the jack removed, so the balancier CAN carry 
some of the weight all the way to escapement).  
   Having the drop set too low will create a larger zone before let-off where 
the pianist must play against repetition spring resistance. This will 
certainly interfere with pianissimo control, particularly when playing rapid, 
soft passages.
