Checking all measurements three or more times from both directions usually catches those for me, but then one day it's surprise time. I even use a simple little spreadsheet input form that I measure hitch to bridge pin and hitch to agraffe with the speaking length calculated as the difference. So when I look at bichord pairs and see a 5mm difference in speaking lengths, which is my typical screw up, I have an easy cross check. That doesn't help on monochords, but I'll take whatever help I can get. Charting speaking lengths is a quick and easy visual indicator of suspicious discontinuities too. You probably already know this, but though it's functionally a non-event for the small distances involved, different string makers handle the hitch differently. One will use the back of the pin, and another the center, and their respective supplied measuring tapes read differently as a result. So they need to know hitch size as well. Seems overly complicated to me when the back of the hitch pin is where the loop seats in all cases regardless of hitch size, but that's the way it is. They also handle elongation a little or a lot differently. Some not at all. Ron N
