Based on that theory any GM could be cheating OTB. And every previous fastest rise in chess would be a new record and thus unprecedented. But even for your theory to be true you still need all the additional components thus adding to the complexity of the theory to make it work.
Only two components are needed to make that cheating method work: a device, and an accomplice.
Stage magicians / mentalists already use this technique - so it's not as implausible as it may seem. The device (and the technique itself) is called a "thumper" - a small, flat device (usually concealed in a coat pocket) that sends discrete vibrations to the stage magician - signals from the accomplice.
This way, the magician/mentalist can appear to have "magical" powers of perception - possessing answers and insights that seem impossible to have.
The only real difficulty here is finding a device that can elude the Garrett SuperWand. (That part of the theory is beyond my knowledge ...)
Though, if (hypothetically) a player truly wanted to, they could purchase the Garrett SuperWand online.
Then they could use it to scan their cheating equipment, to see if their method is detectable or not ...
#81: A better result to hypothesise about is Niemann's FIDE rating. There's a lot of evidence to take into consideration. The best and simplest explanation is the one that best matches that evidence. It's just common sense so there's no need to invoke Occam's Razor unless someone wants to appear clever to people who haven't heard of it before. There's no need to back it up with university degrees unless they're trying to convince others that the logic is less trivial than it is. If they've done the data analysis themselves then I'm interested in credentials but no credentials are required for watching YouTube videos and posting an opinion on these forums.
