You don't cite what or who you are speaking to so I will infer that it includes my comments.
The only thing I said that could be considered judgemental is that the defacto statements made by others to do their own VIP inspections do not constitue sound advice for the OP or any random reader browsing this thread.
There absolutlely, positively are scenarios where a DIY VIP will not get you a fill, that is a fact. Anyone considering doing their own inspections just needs to realize that, evaluate their local situation and go forward based on facts.
To simply say "do it" is setting some percentage up for failure.

I took no exception to any of your previous posts which all made sense. I was hoping the "revenue stream" comment was not an all inclusive comment as to why some shops don't take DIY stickers.
The nice part about accepting PSI/PCI certified inspector's stickers is that they have been trained and received a certification. Those inspectors have an obligation to perform a very specific inspection and take on a lot of the liability if they don't. As we all know, however, a certification does not guarantee competency. On a trip to a recent shop I had a discussion with one of the VIP inspectors who had a SDI/TDI? class for about 2 hours and $100 from a local small hydro shop owner. She was beyond clueless about what she was looking for. She had no clue that there were set limits to pitting and other basic things.
