I do believe there can be a gap between your slower games and faster games but what would be a reasonably gap?
Because i dont think 1100 to 1900 would be a reasonably gap. But lets say 1650 in daily and 1900 in blitz, that would to me sound like a reasonably gap.
Can a 1100 (daily rating) be better in daily then someone rated 1900 in blitz and bullet?
Background story to this question is that I am having a conversation with a person that saying that someone rated 1900 in blitz can be so bad at slow games that he only got 1100 in daily. Im new to chess and have only played a year, but for me its hard to believe that you can get to 1900 in blitz and then struggle to beat 1100 in daily. Because in order to get to 1900 in blitz you have to be good in chess.
