After the original question: "Will Advanced Blind Methods Become the Best Speedsolving Method for Humans?".
I assume you meant for 3x3x3 average of 5 in competition (or ao100/1000 at home, etc), and that "humans" means either most people, or the top 3x3x3 solvers; rather than those who "quit" CFOP to focus only on 3-Style, in which case, they could end up faster with 3-Style method than anything else.
For example, Jack Cai says he's faster at 3-Style method, but I doubt he practises CFOP at all these days so I don't think the "CFOP vs 3-Style" comparison here is quite fair since they're different tools for different jobs. Sure, you could use an old hard drive to hammer in a nail, but on average, a hammer will get the job done better. Similarly, you could use a hammer to record data or basic information in a pinch, but again, the tool that's designed for recording data will be better at it on average.
As for 5-Style, I don't think relatively normal people would care to embark on this journey when CFOP/Roux is almost a guarantee (for many dedicated speedsolvers anyway) to sub-10 given sufficient high-quality training and practice. Is there a course for full 5-Style that people can complete in a finite time while not neglecting other responsibilities or hobbies? No. So until there's evidence of it actually working in practice, maybe it's better to lump it in the "beyond advanced" category, and assume "advanced" means 3-Style and nothing more.
Anyway, there's a simpler way to look at this: Observe the current best 3blders - Tommy, Elliott etc. (apologies for omissions), who of late have gotten really good really quickly. Time how long their exec takes. Is it *consistently* 5, 6 or even 7 seconds? Why not? It's not like they pause all that much amidst all that high tps turning.
It's the move count.
