The last puzzle you missed was rated 1254. Since your puzzles rating is 2300 something, missing it cost you 21 points.
You are supposed to be able to get practically all of the puzzles rated 1000 points below you correct.
It wanted you to supply 4 moves after 1..Kg6. To do that, you have to see the mate in 10.
I'll admit it isn't that easy.
I'm not sure, but I noticed that the amount of rating you lose is significantly more than the amount you win, like, a lot more. The amount is 5 times as much as you win. I had a 2500 rating in puzzles, and I went down 197 rating in about 10 to 15 wrong puzzles because every time I win, I gain 5 points, but when I lose, I lose about 26-28, which is a huge difference.
In a math expression, it would look like this.
28 / 5 = 5 R3
26 / 5 = 5 R1
this has also been happening to me when i was 1700 after losing about 15-20 puzzles i dropped significantly like about 400+ rating lost.
at the end its very hard to choose i mean i don't know much about chess.com's system but have you guys had the same problem?
