Fencing. I’m a “hobby athlete” at fencing (Sabre) and I’d play with about a 10x point multiplier if I wanted to compete with an Olympic level athlete. We had a couple people like that at our club.
That's comparative performance vs. absolute performance. Yes, there are people who can beat others 10x more often than those others can beat them. That doesn't mean they perform 10x as well. In fact, it can be enough for them to be just slightly better in order to achieve such comparative results.
Where absolute performance is concerned (that is, performance measured against an external, objective standard), no elite athlete in any sport is anywhere close to 10x'ing their hobbyist peers. Even beating them by a factor of 2 is unthinkable in most sports.
