Tactics Trainer ratings bug ?

I've just noticed a peculiarity in my tactics trainer ratings that I can't explain.

For example

DateID#RatingMy RatingMovesAvg. TimeMy TimeOutcome
Sep 25 8:39pm 0040113 949 989 4/4 0:51 0:33 Passed (87% | +38)
Sep 25 8:38pm 0037847 881 951 1/2 0:18 0:25 Failed (31% | -34)
Sep 21 9:40pm 0028809 783 1066 1/1 0:17 0:10 Passed (88% | +16)
Sep 21 9:40pm 0028832 900 1050 2/2 0:18 0:06 Passed (96% | +32)

So today when I started doing the tactics trainer my rating was 1066. After 1 problem which I got wrong Embarassed and from the outcome I assume that my rating should have changed by -34 but it appears that my rating changed by -115.

Have I totally misunderstood how it works ? Totally lost my marbles ? or is something not correct ?

It does appear that something is amiss here. We will be looking into this. Thanks for pointing it out to us.

Are you aborting problems?  Those aren't recorded, but still lower your rating.

Aborted problems are recorded, they were just being displayed out of order. I've now corrected this so you can more clearly see how your rating changed:

Hmmm. I didn't intentionally abort any problems but I now understand what's happening and will keep and eye on it.

Thanks for the info

If your rating is 989, then how come you play with a rating of 2230??

I stopped playing the tactics trainer over 6 months ago as you may have noticed if you'd bothered to read it.

It's also far easier to decide on a move with 3 days to make a decision as opposed to less than a minute. I'll make no apologies for being crap at speed chess but I definitely object to being called a cheat. If you have some evidence to back up your claim please feel free to share it.
