With close to 4000 merits, you definitely are one of the profiles op is referring to.
Concerning the quote above, it's not something you can deduce instantly by the merits the profile has. You have to consider that at the time when merits was introduced in January 2018, merits were airdropped to users only on their activity then, not quality (bear in mind that, some of those users have not earned any after that). Accounts also change hands sometimes; users farm accounts to high ranks to sell them to others who may/may not be quality posters. That being said, other than this, merit score can be used to come to your conclusion above 99% out of 100.
