I think that higher rated person have also 99 or 98 accuracy, but simply is faster. Hikaru in most of his games has more time than his opponents for example.
I am getting confused here. Person 1 says the chess.com accuracy percentage is based on caps. Person 2 says something contrary that caps is better but doesn't say how it is better. Person 3 comes along and then says something about time being a factor in accuracy. Is this true? How can making the right move in less time be "more accurate". That's like saying someone buys groceries more accurately because they got to the checkout counter quicker.
Nakamura might be more efficient, but playing faster doesn't mean you are more accurate.
