No one actually knows how to lculate what speaker cable they need

In a market that is loaded with schemes, awkward tells of directional wires, skin effect and many more, cables that goes for thousands and tens of thousands of dollars, you really think that giving away this formula is a brilliant idea, to satisfy your personal need to know?

Did you ask for the formula from other sources, that are in the industry and tell those awkward tells of directional wires, skin effect and many more?

Most, had buy the story (with the cable) without the formula! Because there is no formula for those tells. The only formula they have is marketing and cash flow.

Would you use the same method when you are driving your car to an unfamiliar place? Just drive and drive without any particular direction, till you find it (or not). Willing to pay the money and time?
Well, most would just use a GPS NAV device, enter detonation and pick the fastest or shortest way to get there. That's seems to make more sense to me, than just driving without directions.

As with GPS NAV, with a formula and science, you can get the right and optimal cable on your first attempt. It will save you the time and money chasing that till end of times.

Because even if you are there (not knowing) you may continue the journey to find a better one, that do not exist.

Good luck and enjoy, your blind folded search.

I hope that when it will get to a cure for a disease, you will find more effectives ways to get it. It may also be an eye opener for other things in life, you try to solve.
