This reminds me of when IR cameras started to become affordable. Back when they were $30,000 only business who were serious about it would buy them and they would send someone to the week long class on how to use them. Once the price dropped, people (non-businesses) and smaller business would buy them but not invest the time or money in the week long class. The next thing you know, there are a bunch of false readings being reported because people don't know how to configure the camera or understand things such as emissivity or reflective materials. I'm not an expert at reading bore scopes, but my gut is telling me that if they shoot well, not to worry about it.
