Why high-end cable manufacturers don't post measurements?


I'd like to get your take on why high-end manufacturers don't post measurements? would you like to see how a cable measure before ....does it matter to you?

BTW, as a point of information, battery cable is so very 2019, whereas welder's cable is where it's at now, it's flexible, and you can get it in 0, 00, 000 and 0000 thicknesses.

I prefer MCM / kcmil guage for truly reference cables that are good up to a mile. 
I have a very good friend who actually sells real power distribution systems around the world (think electrical infrastructure for cities of 11 million and then some). If you guys continue with this wire expertise, I will have to call him in for help.
speedbump6: I did not say every. I said specific. 

For example: In another thread, I stated the requirements for sub-woofer controls and "Among others, the Martin Logan x series have all of the above."

Almost every other responder recommended what they own. 

¿Comprende, amigo?
People get criticized for recommending what they own( why wouldn’t they if they went through a process to determine what’s best for the goals they set?) and for recommending product they don’t own. Also if it’s something they’ve never listened to, but based on lots of info from others posting. We are having discussions, conversations. Most understand that everyone has different likes, so they mention what they think someone might like based on what they said they’re looking for ( or sometimes recommend something completely different just because they like it, whether or not it fits with what was asked for) sometimes having a discussion enlightens us to things we had not considered before, it has sure happened to me. You did say something earlier that intimated no opinions were of value, or at the least most, or so it seemed. Sometimes the way we word things appear different to readers than how we perceived it when we posted it. I’m happy to listen to opinions that are given in good faith ( not ones telling me I’m hallucinating when I hear something) I believe I can get a feel for the basic idea of what to expect from others descriptions, though I did recently buy a guitar amp based on what I heard online and what was posted individuals and professionals. I’d say it’s the first time what I expected and what I heard in person was different. Barely spent any time playing with the settings yet, so jury is still out.
