I think I have had the bins measured 4 times in the last 20 years and 3 times the adjuster figured a few less bushels in the bins then I had figured. One time he was about 1500 bu. short in the first bin and about 500 bu. more then me in the next 3 to end up almost exactly the same on over all bushels but different then me in every bin. One time out of the four the adjuster was really working for the insurance company and I had to argue with him and measure the bins a second time before I finally gave in, but at least it was closer.
