1000 is considered to be semi-advanced and takes years to achieve.
You can get to 1000 in a few months....and 1300 is not very hard but it take a lot more games...but you need to carefully think on each move on both side and study the basic endgame and tactic and opening.
When analyzing you are supposed to write out all your thoughts, look up stuff, and check for errors. That takes at least 20 minutes or more for each game. Lets say it was 150 Games. That's 3000 minutes. That's fifty hours. That's a full-time job. I highly doubt you are spending that much time analyzing your games. Don't take this as bad-mouthing you. Take it as constructive criticism. Start analyzing longer and do these things. This doesn't include analyzing with a coach or stronger player. This also doesn't include analyzing with the computer. Combined with those, nobody has time to do this for 150 games in a month.
