Tactics Trainer: Selection algorithm

Sort:
Avatar of M_H_R

Hi,

The tactics trainer used to select problems randomly distributed around my current rating (which is what the help on the topic says it should do). However recently, I keep getting very low rated problems, no matter what my rating. I took the liberty of plotting the distribution of the recent problems, and it seems to be randomly distributed around 1800. This makes it almost impossible for me to get past 1950, at which point get 3-5 points for a correct problem, and -21 for every incorrect one. This problem started recently, since I was still recently rated above 2100.

Regards

Marius
