If it was a cylinder with a lip protruding from the top, I was suggesting
that the cord be wrapped around the cylinder, not the top. The diameter
could be of the top, including the lip.

I think this is more of a problem. I haven't seen a convincing solution to
it although I have seen it mentioned in commentaries. Errors in
transmission of numbers is not unusual, and it may be that there is
something we don't understand about ancient measures, not necessarily
something that the ancients didn't understand.
