Hi Jack, When calculating action ratios, I take the first lever-arm to be from key-top above the font pin. Some do their ratio calculations from the key front (I believe Pfeiffer did). When setting the key dip, it is easier and more convenient to take it from the key front. Just my take. It was nice to meet you at Rochester. Have a good Christmas.
