It's comparing players of the same rating today vs. the past using the chess engine Stockfish to analyze how well players are a certain ELO performed. For example a player with an ELO score of 2000 today is stronger than a player with an ELO score of 2000 back in the 90's.

You're totally off with your numbers. I don't know anything about college entrance exams so I won't comment on them.

If you play football in the NCAA you need to be closer to the 98th percentile to have a shot in the NFL. And to even got a shot in the NCAA you needed to be in the 95th percentile of high school players. In the NFL even the never gonna make it cut from the practice squad guys are in the 99th percentile of all people playing football.

There are over 600,000 restaurants in the US alone and less than 3000 Michelin star restaurants world wide. So we're definitely in the well over 99th percentile there.

As for websites. There are an estimated 1.5 billion websites in existence. That means to be in the 95th percentile you only need to be in the top 750 million websites.

So yeah, the example you give are a actually a pretty strong case for the 95th percentile not being that impressive.

I don't think it's just that. I think a lot of it is just a desire for successful results. Once you learn how to do something and it works you don't bother with asking if it's the most efficient way or not. You know it works so you just keep going back to the well. You then spend your energy on figuring out the next thing you don't know.

Except those "better bookstores" are also struggling. The internet might not be killing physical book sales, but online retailers are killing physical book retailers.

I think the conversion is somewhere around 1 pound to 1.30 in dollars. So 26k for training and 52k afterwards.
