Puzzles rating seem broken


There are some updates on puzzles. One is that the puzzle's rating in the interface is different than what's being used on the back end. The system was updated to set the ratings to be more accurate.
The site also is trying out some different puzzle selection algorithms, and it's possible you're in a group that's getting lower rated ones on average, based on the new backend ratings, and missing one has a bigger impact when it's a lot lower than your current rating.
The system should have the backend ratings reflected in the UI soon and the site will likely settle on a new standard selection algorithm soon too.
