I actually thought this was real for a moment, until at the bottom of the text it said "Happy April Fools" and then I knew it was a joke... lol

Glickman's definition of Glicko-2 states:
> To apply the rating algorithm, we treat a collection of games within a “rating period” to have occurred simultaneously. Players would have ratings, RD’s, and volatilities at the beginning of the rating period, game outcomes would be observed, and then updated ratings, RD’s and volatilities would be computed at the end of the rating period (which would then be used as the pre-period information for the subsequent rating period). The Glicko-2 system works best when the number of games in a rating period is moderate to large, say an average of at least 10-15 games per player in a rating period. The length of time for a rating period is at the discretion of the administrator.
Therefore, I ask: what is the duration/length of Lichess' Glicko-2 "rating period" at the end of which, all games played during that period are concurrently (not serially) rated?

I request my points :p happy april fools!
Now I understand everything. My FIDE rating got 200 points higher, and I thought it was a bug. Thank you for this explanation.
Happy April 1st! :)

Confirmed- I got my first FIDE rating today and its nearly identical to my Lichess rating.
I actually thought this was genuine and literally almost got depressed cuz i have a fide id but no rating then i realized its april first
I didn't get an additional rating that identical to my Lichess, can you explain why?
