My study was mainly on master and advanced players, as those were the only data points I could use. You only have 85 games right now and are ~1300 rated, so I'd suggest playing a few more games and finding your level.

In many data sets, you'd often find statistical anomalies. So this isn't anything special.

Reg. the blog post, ELO isn't just another word for ratings in general. It is just a system of ratings. Online platforms usually use Glicko or Glicko-2 rating systems instead. (Lichess used Glicko-2, albeit modified)

You can't compare real FIDE Elo, with online rating. Do you understand those are different things?

Genuine question, what makes them different? Isn't it a similarly functioning algorithm calculating things under the hood?

I analyzed BLITZ rating. Please read the post title and read the post itself before saying something stupid. This analysis is for master players who are active on both sites and have an established FIDE ELO that I can 100% know, as per the data set.

I understand the difference between them because I've been playing chess both online and in FIDE for over 9 years. Explain why you "can't compare them," please, and I might be able to grasp your viewpoint.
