Does it not also set a limit to the amount the hammer physically falls after let-off-not on a struck note, obviously, with hammer rebound and repetition lever "cocked," but with a gentle, non-play press of the key-therefore truly a "regulated drop?" I'm sure that's where the term came from; maybe your term would be more descriptive of the actual mechanics. Does it not also, if set right, prevent hammer "bobble" or double-strike if the backcheck doesn't catch the hammer on a light blow? If so, let's call it the "Hammer Anti-Rebound, Drop Regulation, and Repetition Lever Upstop Screw" or HARDRARLU Screw for short. Maybe not.
