HI in general is just a way to force a seller to lower his price. I guarantee the buyer doesn't want the voltage drop fixed, he just wants a credit on the price equal to the work the HI recommends.
I do see some silly discussions over on the NACHI BB trying to make mountains out of molehills. I suppose if you pay someone $300-400 to give you a 2 hour inspection they feel obligated to find "defects". They argued for a week over multiple ground wires in a single lug on a bus. They lose their mind if you don't reidentify a white wire on a romex used for 240v. You would think babies were dying all over the country from this "defect"
