You just now realized this?
The way I see it, cheaters in standard made a glass ceiling around maybe 2000. It looked bad when some master has a 1700 standard rating. So they pumped up the higher rated players by 400 with the goal of attracting more players in the short term.
Which... probably accomplished that goal to some extent. But players who have been here will just laugh at it.
Standard ratings are not inflated. They are similar to OTB ratings.
Blitz ratings are strongly deflated. I will never lose to a 1200 in real life, but I lose (sometimes horribly) to 1200 blitz players on chess.com pretty often.
standard ratings are horribly inflated. the 1600s here play like absolute beginners, OTB is 10 times harder.
blitz ratings are probably only 100 points higher than USCF and maybe around 200 points higher than FIDE. but standard is literally 500+ points overinflated compared to USCF.
