Rating increased by 200 points in 5 weeks

This is only my personal view and it is based on wanting to improve rather than just play for fun, which is of course fine:
Firstly, I think that it is necessary to do exactly the same thing at the same frequency (daily, 3 times a week, weekly…) so that the metrics and graphs are linear. Playing 20 games one day and 3 games on another random day makes it almost impossible to measure progress. I decided on 5 games daily based on what time I wanted to dedicate to chess.
I play exactly 5 games. If I win every one, I don’t continue because I seem to in good form. If I am losing every one, I don’t stop because I seem to be in bad form, nor do I keep playing until I win to try to recover. You can’t choose the day or your form in a real chess game!
Six weeks ago, I had never played a single game of chess online only being interested in OTB chess but after almost a year without a game and at home due to Covid lockdown, I decided to finally register with an online website.
I decided to concentrate solely on 10+0 games. I need to calculate because my instinct is not strong enough for anything faster. The first few games were a bit flakey because I didn’t find it as clear as looking at a proper board and I was prone to the occasional mouse slip. I also found that I couldn’t give the same level as attention to a computer screen so was half-watching a movie at the same time and not always even registering that it was my turn.
I have never really done chess puzzles previously other than occasional ones that members might pose at a chess club. I played around 30 rated games a year but no games outside of that.
Since joining, I have established a routine for two or three hours a day and In 5 weeks my rating has gone up by 200 points! Puzzle solving has improved dramatically.
Happy to share the experience and tips if anyone is interest.
