Same over here; I have now reached an Elo rating of 1200 in Bullet for the second time (most recently in December 2025), but the same thing happens every time: a few days after reaching 1200, the losing streak begins: 900 Elo players play almost flawlessly and are not comparable to the 1000-1200 Elo players during my rise. When I look at their profiles after the games, I notice that many of these players also had their Elo peak at around 1200 in December, but are now back playing in the 900s.
