Coool, a mystery - i don't have a clue and i would like to know the answer too. Something about the puzzles rating distribution? would that tend to keep the distribution in a certain shape, if some puzzles had a fixed rating? maybe so
How is this puzzle rated as 2200 !?

I was playing puzzles and I saw this super easy puzzle was rated as 2200 ! I don't think this puzzle even can be rated +1300 as the checkmate is really obvious.
Also this is another 2200 puzzle I saw but again it was obvious and at most 1600
These have been rerated
