Bad logic.
You're making the same mistake that all the baseball guys in my youth would make when they parroted the common, "Baseball is the hardest sport because batting has the highest failure rate of any sport in existence!" Or they would try to argue that batting in baseball was the hardest thing to do in sport because of that. Yeah, look it up, they've been harping on that forever, I'm sure you'll find some asshole who has chattered about that online in the internet age because he heard it over and over as a kid.
They overlook the fact that this would make pitching one of the easiest things to do in sport because, presumably, you have one of the highest success rates. But even looking past the humorous oversight on their part of the zero sum conception of success they're echoing, it doesn't hold up, because obviously, it all depends on how you define that success.
A batting average of .400 in professional baseball is extraordinary. So that's a 40% success rate? Thus a 60% failure rate? But 0% of humans outside of one man in history have successfully run a marathon in under 2 hours (and he hasn't technically beaten that mark on an official course). That's an extraordinary failure rate. So obviously it's far harder to run a marathon in under 2 hours than it is to achieve a hit against an MLB pitcher. What percent of human beings could walk out and dunk a basketball, or casually hit 105 NBA distance 3-pters in a row the way
Curry has in practice? How many could "bend it like Beckham" from 40 yards into even an unguarded goal? How many could hit a 120 mph serve with that tennis racket?
Because gymnastics is only impressive in this regard because our minimum ceiling for what you're perceiving as "success" is higher than what it is in most sports. But so what? You're thinking of this in terms of replicating the feats of what
elite athletes can do. All those casuals can't do on a soccer field or basketball court or tennis court what elite athletes do. Any of us could walk out there to spasm around on a floor, and call it a gymnastic floor routine. Same thing as some idiot running around throwing a ball at a hoop on a blacktop over and over.
