If you have a key accelerated to a certain speed in the first mm of key travel, it takes very little energy to keep it there... momentum... fine.... Seems to me that when the key is engaged in most cases that the greatest portion of its end velocity is reached within the first mm or so of key travel. From that point on to the point where the key bottoms out on front cushion, most of the work is already done, and the inertia of the key helps to keep it that way.... no ?? So you may loose in the first ms, but you win the rest of the way through.... or what ? RicB -- Richard Brekne RPT, N.P.T.F.
