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?

If you want to use high priced ,I mean totally over priced cables ,its your choice.Nice to have money to burn.When you worked for a dollar an hour $40 a week 50 years ago.It make you question everything....Think about it there are people  here who would never buy a $40 cable ever ,ever,never....
Well,

I chose to believe in the concept of small diameter, individually insulated multi-strand, to minimize the 'Skin' effect of single or twisted strands of non-insulated small diameter strands. (Cat 5 like, what I use)

excerpt:

" Skin effect in audio cables is the tendency for high frequency signals to travel more on the surface than in the center of the conductor, as if the conductor were a hollow metal pipe.[3] This tendency, caused by self-inductance, makes the cable more resistant at higher frequencies, diminishing its ability to transmit high frequencies with as much power as low frequencies. As cable conductors increase in diameter they have less overall resistance but increased skin effect."

from:

Idea, all frequencies travel/arrive in closer time relative to other frequencies, on a minuscule level.

I also believe the reason Analog bests Digital, is the minuscule difference of Analog's ability to get the overtone's timing perfect to the fundamental (despite analog being noiser, my R2R beating my LP, which beat CD)

Surely they have they the ability to measure it's existance, have they published the true measurable difference/advantage compared to ordinary twisted? 10' length? 20' length.

It would be helpful.  Some cables' measurements fall outside the normal parameters, and can cause oscillation with some equipment.  That could be avoided, for starters.

I presume because they don't want to start some specmanship war, or to avoid people buying according to what they think are the optimal measurements for the big three (capacitance, resistance, inductance).

Probably because some very costly cables are very poorly engineered.

Probably because some cables measure very strangely, and the companies don't want/know how to explain why they perform well.

Etc., etc.

No measurements?
Those guys don't understand the product, the requirements, the way it works, what cable is required for each system...They know nothing.
On the other hand, they spread false information, about cables properties, as directional, skin effect, geometry, copper purity etc'. None is relevant. When looking deep into those claims, they hide ignorance and deception. 

So what matters:

A cables resistance equals to the elements constant (copper) multiplied  by length (m) divided by cross section in mm2.
That resistance (R) should be in relation with the Amp's output resistance (Ro) or it's other name: Damping Factor (DF). 

The manufacturers never said a word about it. 
So what kind of measurements should they do and provide information about?
Fair Question. I would like to know why some manufacturers will not reveal the AWG of their product?  Is there a particular reason that a manufacturer would not let you know the AWG of their speaker cable?
