How did I get a rating of "Based on your move choices, our estimate of your Elo rating is 1680, with a 95% confidence interval of [1541...1819]." when my chess rating is only 1188 or something for blitz on this website.... I can't even beat dash the reindeer (came to an 8+ endgame with same amount of pawns, had no clue and did not know the endgame so lost).
how did i get a score of: Based on your move choices, our estimate of your Elo rating is 1837, with a 95% confidence interval of [1709...1965]. my uscf rating is about 550
I got 1775 but my ELO is 1000
