I think if you ever fall below 400 elo you have literally zero chance to climb back and here's why:
1) I've met people with 3000+ games who are still on elo 300. How is it even possible? I don't know
2) I am myself below 400 elo and I'm noob but I encounter people with 3000+ games and they tend to destroy me

1.skill ishue not always true
2.study study study
2.basic checkmate patterns seriously those endgame studies will help you conversion is one of the most important skills
3.checks captors attacks
4.ask yourself what will my opponent do
5.phycological resilience
6.arguably more important than tactics (not always lol tactics prob more important in lower time controls like blitz )
7.of course study openings endgames and middle game
something true (which is the reason I quit for a year) I only get at most 10 rating a game but on my alt account (Which is at 700 Rapid that) I get 40-50 a game Does anyone know why
That's I believe something to do with provisional rating (yes ik thats only the first 5 games but it still applies ) newer accounts gain more elo if they do not play a lot of games most likely to try to guess their rating
The more games you play the more the elo gain goes down until you get the normal +0 to +16 elo
