But, you must realize that the vast majority of people who have solved a cube haven't been to a WCA competition before. The estimate is that 2% of the world's population have solved one. This would be approximately 150.5 MILLION. Which means, that if you can solve a Rubik's cube in 30 seconds, you are better than 100% of people who have solved a Rubik's cube.
1. The post to which I was replying explicitly said 'cubers who had competed', not anyone who had ever solved a cube.
2. Where did you get 350 million? I found a quora thread where someone asked for a number, but the person who proposed 350m had just guessed and didn't even do their math right.
150m would mean that almost half of everyone who had ever gotten a cube has it solved, which is subjectively false as most people I meet have an unsolved one. Their estimated 2% would apply to the 350m cubes sold and that only gets you to 7 million.
And all of that was guess work so it's not verifiable either. This is why we work with competed, because there is an actual, current number: 136,857
3. This is also assuming that anyone who hasn't been to a competition is slower than 30, which is verifiably false: I averaged 25 before I competed and many people averaged sub 20 before competing.
4. 100% means you're better than everyone. Unless you're Feliks of Yu, you're at best in the 99%
