Yeah, you are doing better than me after 2 years!
I started at around 1300 and went up by about 100 points every year. Slow learner, lol.
I got stuck at around 1700-1800 level for a while. In the last 2 years I studied openings and reached 2100.
Blitz, I still cant get above 1900. It takes a lot of natural skill (logic, judgement, calculation) and speed of thought to do well at Blitz. I think it suits younger players and I am now 44
I have only been playing for 1.5 years
