Zero Friction calls it a “protocol”…in the link you provided. I spent decades developing and writing protocols. I know what a “protocol” is and how to write one. It should have detailed step-by-step instructions with evidence that the protocol works. Each step should be extensively tested to see if it works and, more importantly, if it is necessary.
I assert you are wrong. There is a lot of information provided how testing is conducted and they apply it consistently from chain to chain. Free. No charge. Admittedly, the website is sloppy and one has to read a little bit.
That’s your opinion. I agree that the website is sloppy. It’s hard to read and you have to wade through a whole lot of extraneous (and repetitive) information to find anything useful. The fact that their chain wear results are so far off what most people report makes the information even less useful.
BTW.....what are you talking about comparing their results to mine. I did not routinely ride in the conditions under which they test. I sometimes ride under those conditions and if I do, the chain gets cleaned thoroughly and rewaxed. I also ride in low load conditions, my average power might be 115 watts compared to 250 watts. I rarely push the limits of wear on my chains, if I do, it is by accident. I try to ditch them as 0.5%.
I’m not sure where you ride but I ride in all kinds of conditions. From dusty to rain to snow with touring loads, no loads, mountain biking, and mountain biking with loads. I won’t estimate what my power output is but it is probably average, whatever that is. I discard my chains at 0.75% on a Park chain checker because that’s what the instructions on the checker say to do for a 9 speed chain. I get about 3000 miles per chain. Not what you get but far more than what Zero Friction reports.
I suspect you have spent less time reading how they test than writing a response to me.
Of course I spent less time reading their “protocol” than I did writing a response. There is a whole lot of fat and gristle in that “protocol” and not a whole lot of meat. That’s one of the reasons I don’t pay much attention to Zero Friction. There’s a whole lot of useless material to wade through for not much useful stuff.
