On October 1st my Tactics Trainer rating was 2295, and now it is down to
1794, a drop of 501 points!
     Has anyone else noticed this since Jay adjusted the rating system?

[COMMENT DELETED, nevermind - I misread my chart, but no, mine didn't shift. Thanks for asking!]

a little, but not that drastic.  

Before, my tt rating was about 1950 and fluctuated to 2100

and now its 1800-1950

Yes mine is down.   I was bumping 2400 on the high end before Oct 1st, and now its down between 1750 and 1850.   (not sure why but I've always done better on the higher rated puzzles than the lower ones)  Anyhow, The way the ratings are set up now, you loose more points when you miss a puzzle than you receive when you get a puzzle right.  So it drops much quicker than it climbs if you miss a few in a row.   I find it annoying when I get a run of 3 or 4 correct, only to loose it all when I miss one or two in a row, but in reality its probably much closer to my actual rating.   Either way, its still a good work out.

I'm glad that this wasn't something specific to me - I also was rated around 2400-2500 but now I'm more like 2200-2300.

I think I was overrated so I'm glad to be back where I need to be :-).

If I recall correctly, the average rating in tactics trainer used to be around 1300, but now the average is 1244.  I could just have a inaccurate memory, but I think those are accurate recollections.

If somebody knows for sure what the average rating used to be prior to the change then that would give a clearer representation of the true global effect.

Anybody know for sure what the average was?

It does seem odd that when you miss on the first move you get lose about twice what you get when you win on multiple moves.  and if you miss after the first move it has little effect.

we have tried to move the ratings on tactics trainer down a bit, so they will be more accurate. having lost 200 points in one day last week, i know it can be painful... but the ratings had been inflating for a while, and overall we thought it would be better to get them somewhat more in check.

though, really the #1 point of the ratings is to pair you with appropriate difficulty problems, and this works whether you are rated 1500 or 4300. but anyone who has seen a drop up to 300 points in the past couple months should not be too concerned. but zankfrappa, 500! you should worry! jk :-P

btw, i think the adjustment is still propagating, so don't be surprised if ratings go down a bit more.

as with everything, feedback is welcome.

I'm actually more worried about finding or not finding the right continuation, not some relatively random number attached to it.

Mine rating was 2400 before Oct 1 and now it is 1900 something.

 Yes this is true Natalia.  I admit I had been chasing the rating, but recently I have decided to not move until I find the solution, ignoring the timer and ratings.  Naturally the ratings have dropped a bit more, but my pass percentage is increasing, which I believe is more beneficial.   

How often, if ever, do you guys reset your stats on TT?   I've have left a running total for about a year now, but I'm considering resetting the stats.  Any thoughts on this?

It's not a problem if your rating is 30, 400 or 2800, the main question is "do you recieve problems corresponding to your level?" If you constantly get to solve very difficult problems, then this is indeed an issue. Likewise, you should not receive many problems you feel are too easy.

Why is there a rating? Its because: I want to know, do i improve ( or not ) ! I do my exercise and work and work and my rating drops. Sh..mpftgulp..t. This might scare beginners away. I would like to suggest to put a notice at TT that there is a ratingsadjustment running.

There are a lot of Tacticians wich keep their high ratings because they dont do any puzzles anymore. The top rated 1-100 seems to be frozen since months. I think Tacticians with an RD > 120? should not be listed in the statistics anymore, or their ratings should be adjusted to.

I still have a rating of 2300, thats still to high, i dream about such a OTB rating in my sweatest dreams ;-)

Now 3 day later:

Avg Rating Players: 1207

Average Rating Problems :1257

Ratings still decreasing

THANK YOU NATALIA, I WAS AFTER THE NUMBER ALSO....!, but you are right solving  the problems is more important....

It is a good training aid the problems at my level are good. I am about 1300+ but I find they are quick for me as I am slow at these.

I will loose no sleep over my rating but I will keep on doing them

Phew - thanks for this post.  After months of practise, I thought I'd suddenly lost it, and was just getting worse and not seeing anything.  Now that I know the reason for the decrease I can get back to work with renewed confidence.

Yeah, I noticed quite a difference. I just presumed that's what had been done.
