It’s a common misconception that it was even called Ev to begin with. In reality, it used to be named Mt. Eh due to how underwhelming it is.

“Constant average query time” is not that hard to understand. It means that sometimes access time is e.g. linear, and sometimes you get your content before executing the code. With a hash table large enough and full enough, this can be used to fetch content seconds, minutes, days, potentially years before the program even exists. That’s one hell of a breakthrough.
