This is most logical to me if you don’t need absolute accuracy. If you wanted more precision you should also be reasonably able to estimate the spool circumference increase in relation to the length (after x revolutions, increase diameter by y). Yes this is not perfect as diameter will require increasingly quantities to “grow” but.. close enough?
