When a brand markets their pad/rim combination as a "system," what do you interpret that as? It's a mechanical system, not a chemical one, so there is no reaction taking place between the pad and the rim. So this means that it is simply friction converting energy to heat. A rim will be made with a resin that has specific glass temperature properties, and then a pad will be assigned to it that has a low enough coefficient of friction so as to not heat the rim passed the resin Tg. This is the "system" you are referring to, nothing more.
This means that an accurate comparison of rims must use all of the same pads, and it can be any pad! If every rim used an Enve pad, that would work just as well and the results would be the same. The test may just take a bit longer to run.
As we mentioned in the disclaimer, we were not trying to emulate Enve's internal test or see how anyone's rims would do with their brand specific pads, we were just trying to get an apples-to-apples comparison of composite quality, and that's what we accomplished. Our internal test is an interval one that includes rest periods so that we can see how our own rim will heat and cool in real world situations, but it's an entirely different protocol.
You're absolutely right, time will convince the naysayers of our rim quality. We try to be as open as possible with information and testing to prove that it isn't marketing, but there will be some people who are never satisfied. That's ok! We are only 3 years old but we have some pretty great engineers, two design patents, completely proprietary manufacturing, and zero recalls to date. That's a challenge for any brand, and our track record of performance and safety will certainly speak for itself.
This doesn't read like someone who's actually gone out and ridden several different wheels with several different pads.
I'd be more interested in stopping distances with the same force than how long it takes to blow up the rim. Not that I'm interested in carbon clinchers, but I do need to do hard stops on carbon - I have never needed to drag my brakes for even a minute. And having ridden nearly every wheel in your test, my experience with braking power is almost the inverse of your results.
Also, your confidence is great - but zero recalls on a wheel I've never heard of, let alone seen in the wild, doesn't really seem statistically significant.
