The article presents a method to estimate the repeatability of a destructive measurement instrument using two different item types with equal variability. The researchers found that by measuring these two item types and making certain assumptions, they were able to calculate the repeatability of the instrument and determine a confidence interval for this value. This method adds to existing techniques for estimating repeatability when repeated measurements are not possible.
