3 year old (inactive) FIDE rating of 1870 FWIW.
I read somewhere it takes 90 days to build a habit. I've also noticed (maybe by coincidence) that it takes ~90 days until muscle memory feels >90% of what it used to be.
Still, it's mostly a guess, but I'm thinking it will take ~90 days for me to regain reasonable analysis habits.
All this to say, I don't know what my playing strength is. Plan is to do some analysis and some long online games for a month or two and then go back to tournaments... and regardless of results not beat myself up too bad until 90 days have passed ;)
I once gained 100 points in a year, does that count for something? lol.
Yeah, that rate of improvement is impressive no matter who you are. Sounds like he has talent for the game. Also sounds like he had good help.
I want to make 2200 in 2 years. Someone reading this contact me and make it happen
About FIDE arena I'm wondering, in terms of practice, how it would be different from 45/45 games (or similar) on ICC? Cheat detection or prestige maybe?
