Ken Sloan wrote an excellent clarification regarding the consequences of higher leverage shanks. Ken, you located my confusion exactly: efficiency of leverage means less effort but the distance travelled in key dip is longer (the arc travelled further from the fulcrum is longer). Isn't it also true then that the speed of travel must be greater as you move further from the fulcrum to result in the same speed of travel of the hammer? To move the key (from top to bottom of travel) a greater distance in the same time span the finger must move faster? But if it takes less effort you don't feel the additional speed?
