Your analysis and conclusions are very accurate, and I think many people follow your insight when it comes to filtration and the constantly moving ecosystem of oil filter cheaping and defects by so many companies.Everyone in the group will have some kind non-agreements to some level. There were people when Purolator media was tearing constantly who said it was "no big deal" ... viewpoints on stuff like this is all over the spectrum. And lately, many don't care about a leaky leaf spring ... I say, whatever floats their boat and makes them feel good about their decisions is cool. I base my choices on my own decisions and conclusions of info and data posted and discussed.
It might be helpful to many of us if you could share with us a list of filters that you think have no defects and have close to 99% efficiency @ 20 microns that you would recommend.
