In order for the above to actually leave a hammer hitting the string at 90 degrees, it has to be assumed that the string is parallel to the keybed. This is rarely the case in the upper two octaves, where strings rise from the capo to the bridge. A boring done strictly on distance between stringheight and center pin height will often produce a hammer that is leaning distally upon string contact. I use a set of measured borings as trials. That way, I can lift them up to the string, place a square on the string and compare it to the centerline of the hammer, which is at 90 degrees to the shank. This allows me to tell if the hammer is at 90 degrees to the string upon contact.
