Nick has been around the expensive toy scene for a long time. What you're seeing is the difference between someone that ACTUALLY knows stuff and someone that has read articles/forum posts but doesn't really know what he's talking about. I'm no expert, I entered the NOD club less than a year ago. I try to ask questions more often than I lecture, to the point where Chris, Steve and Nick probably get annoyed.
Seems like one of your key problem is word choice. You seem to get inclusive and exclusive meanings confused. You stated OMNI VII and VIII tubes are also known as Pinnacle or filmless. That is not correct, as you are stating that all OMNI VII or VIII contract tubes are either Pinnacle or filmless, which is not true. Pinnacle is a line of tubes made by ITT/Exelis which also makes shit like Everest tubes. L3 also makes contract tubes, they are not Pinnacle. Not all Pinnacle tubes are OMNI VII or VIII. There are also OMNI VI Pinnacle tubes.
Filmless tubes have been around for a while. MX10160B ANVIS tubes were made both filmless and with thin film, depending on the manufacturer. This was as early as OMNI V.
Again, that chart that from AR15.com is a list of minimums, not average. If a tube is made with a contract in mind but does not meet the minimum specs, I'm pretty sure they are sold off to the civilian market.
