Rating score

Hello
I used to play on this website a few years ago and i had a rating around 1200
I started to play again a few days ago with what i believe is the same level of playing, I would even say maybe a little better, but I very quickly went down to 600 !!!
Did they change something with it ?
Is this rating accurate ?
I mean can it be compared with the regular chess rating, meaning you r beginner til 1000+
I play rapid (10 min) only if it's accurate that mean i m pretty noob :-)

Thank you for such an helping message
I could debate, telling you not too worry too much I have a wonderful and successful life or telling you how much a d... you are but I ll just smile and conclude you r a pitiful person :-)
Have a nice day 

Read again my question , you are far from a decent IQ ....

And please just go away, and let someone with a better understanding reply
Thank you, have a nice life :-)

Nah its ok :-)
People live the best they can.

You did not play that many games back in 2020 so your rating was still in flux.  After a long lapse in playing a player gets rusty (generally by a couple hundred points or so) and it takes a while to get rid of the rust.  Playing a lot of games while you are rusty will result in a rapid rating drop.

The good news is that, once the rust is taken care of, when compared to a higher rating your lower rating will mean that you will gain more points for a win and lose fewer points for a loss.  Once the rust is gone you can figure that another 20-50 games will get your rating back to matching your strength.

If I am correct, you've played less than 20 games in 2020. and you got to 1 200 rating. It is not a negligible amount of games, but it is not really sure what your rating actually would be if you've played say 50 games or more. Perhaps you had some good run at that time for instance, or you are having a bad run now.

On top of it, if you didn't play for 2 years, you are probably a bit rusty, even though you believe your level is the same (if you've played somewhere in the meantime, that is another matter).

Along with that, I feel that as the time goes by, you probably need to get slightly better to keep the same rating after a few years. 

Thanks, both of you 
Yeah i probably didnt play enough back in 2020 to be at my right rating, that must be it.
And today i m trying to finally learn and play, after droping at 600, I slowly raised up to 750
I guess it's my level, noob+ ha ha ha

So this ratting  can be compared to that  ?  ( i found it on google )
400 – Your beginner rating- before your first tournament.
800 – You are a player having chess basics right and can independently figure out several threats/opportunities in the game.
1200 – A budding chess player who can understand some basic chess strategies.
1600 – A player among the top scholastic players on a state or national level.
2000 – Expert Level – A milestone hit by a handful of chess players while they are in grade school.
2200 – Minimum rating to be considered a “Chess Master”.
2400 – “Senior Master”.
2500 – Minimum rating as part of requirements to earn the “Grandmaster” (GM) title.
2900 – The World Champion is typically rated closer to this ranking.
3000 – No one has yet attained this in standard tournament competition.

Don’t worry to much about rating. It goes up pretty fast once you start to play more.
