George Fennel (guy in video, and designer of product) is a bit of a grump, but he's likely the most knowledgable person in the field. Those lube testing machines are fairly popular, so you might be able to run your own test if you ask around. That being said, the vegetable oil lubes (e.g., Frog Lube) have never faired as well as others when it comes to lubrication, especially when you start mixing them with other chemicals (e.g., gun firing residue).
