You may have seen it. I use a let off rack as the reference rather than the adjacent hammer which I find difficult. Measure the distance at rest, place the 6mm dip tool and measure again and subtract. Divide the difference by 6 and there's your ratio. You should do it several times and make sure that the let-off button is not interfering and also that there is adequate tension on the rep spring and that the balancier height is regulated so you don't get some unwanted irregularities in either the rest position of the rise position. <o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif"'><o:p> </o:p></span></p><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>David Love<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>www.davidlovepianos.com<o:p></o:p></span></p></div></div></body></html>
