Even in the 93rd percentile, people blunder like dummies.


93rd percentile means you are one of the tallest pygmies in the village.
It does not mean that you are a giant.


Even GM's can blunder like dummies, whats your point. 93rd percentile means top 7pct of players, not that you are 93 pct as good as Carlsen. The skill required to jump from x percentile to y percentile can vary wildly, its not a linear progression. That's why its common for chess players to hit plateaus.

This percentile thing makes as much sense as 1100 players posting how their CAPs score is 99, and then ask if they are a GM?
We dont blunder because we are "dummies". WE blunder because we are human.
