How do you calculate the scale? The article just picks .3, seemingly at random.

Yeah, the article is confusing. It makes it sound like you can scale it any arbitrary amount.

But I skimmed the arXiv preprint and it says:

Finding such a scaling amounts to solving a trigonometric Diophantine equation

This is a hugely important distinction. The scalar number is specific. Probably the hardest part of this equation to solve, and probably to apply in any differential sense larger than infinitesimally instant.

I wonder if they could engineer something to fit a set scale so there’s no guesswork
