Surely they didn't actually test it years after the patent was issued and found it unnecessary. Wouldn't they have to file a patent retraction (an idea that's time has come)? Probably just saving lead. Then again, their practice of individual key leading with whatever the weights and friction levels of the action gave them, would be more easily and "accurately" done with smaller weights further out than with bigger weights grouped at the center. Now that I mention it, how does moving weights in toward the balance rail for better performance through inertia control reconcile with their custom of individually custom leading keys without regard to action friction levels? Doesn't really compute. Ron N
