Chess Rating Deflation

Hey all, 

So I am an active chess player, with a USCF rating in the 1700's. By active, I mean I play or study chess for around 4-5 hours per week, including playing blitz on here or occasionally on another site. 

While I am confident my skill level has not declined, my chess.com blitz rating seems to have gone down around 50-100 points for no apparent reason. I suspect this is a server issue because now that it displays the percentile, my blitz percentile has been steady between the 92nd and 95th percentiles among all users on the site, regardless of whether my rating was peaked (at ~1740 last fall) or seemingly low (~1620 as of this post).

Does anyone have thoughts on this or has anyone noticed something similar?

Thanks

Yeah mine got bumped wayyyy down! I was in the 90th percentile. Idk what the deal is and I think it is a glitch.

This is an issue that has existed for years. A while back a poll showed that USCF ratings for blitz were much more generous than the blitz ratings of chess.com

Your current blitz rating, as well as your trend, is in the ballpark for a 1700 USCF rated player. Nothing strange here.

At least you weren't claiming to be like 2200 USCF - now that would be very weird.

I'm 1730 standard rating USCF, ~1620 chess.com blitz, but only ~1510 USCF blitz! What's up with that lol?

So according to that, you're overrated on chess.com... where's the deflation?

I believe chess.com does overrate blitz players (on average), moderately at the U2200 FIDE level, and then greatly above. That seems to be your case, and although I don't have a USCF blitz rating, I can guarantee you my blitz is pretty bad compared to my standard.

The deflation is that 6 months ago I was over 100 pts higher on here, and have now dropped for no apparent reason, including no decline in skill level.

It's something that happens - your ratings trend fluctuates regardless of your skill. 

Besides, you probably don't train for blitz, but for slow. If your slow gets better, your blitz may not improve. 

While u play 5 hours a week, other players play much more.This week it was opened a post here on chess.com where a person told he studied 17 (!!) hours for day.

17 hours? They need to get a job or something lol. At the bare minimum at least another hour of sleep xD.

No one "studies" chess seriously for 17 hours. They probably study for at max 3-4 hours, and waste the other 13-14.

Lol

My blitz rating here goes down when I play badly, but has been generally rising the past year or two. My USCF dropped into the 1700s in 2016 due to horrid OTB play. I was last that low in 2008.

 No one has the mental energy to study anything for 17 hours a day and make use of all that time.

Well, maybe if they have a mental illness or some other kind of disorder.

Have you tried not losing games? oh and really, you maxed out at 1741 for like a day...relax, sometimes peoples ratings fluctuate and *gasp* go down.

There sadly has been no real rating deflation on chess.com in any single one of the categories (rapid was inflated drastically a few years ago I believe).

The only pools that may be mildly deflated are:

*2+1 bullet - I don't know why, but the 2+1 players seem much stronger than similarly rated 1+0 players. If you forced a single 1+0 player into the 2+1 pool for a while, I'd almost guarantee a rating decrease for the 1+0 player, and perhaps a large decrease.

*10+0 blitz (and 5+5 blitz too) - I don't want to lock this thread, but I recommend no one play in these pools.

Really? 10 is really all i play....i play on my phone mostly, so i lose any time scramble...so i feel like 10+0 compensates. Is it that bad?

Since you're <1700 blitz, I actually don't think the deflation reaches there, for the reason I couldn't say. I'd imagine the massive deflation happening 2000+. 

But there might be slight deflation still :/

All I'll give you is this:

The user I played in my last ever 10+0 game. Check out the opponents in his blitz games (there's like 150 of them), and you'll understand.
