Rating for how you have been playing


The Glicko system used here does take into account how frequently you have been playing. You have played almost 9000 blitz games but have only played 1 game in the last two months. Therefore, your 1437 rating is not as accurate as when you were playing every day.
The Glicko RD (ratings deviation) on your rating is up to 38, meaning that your rating is still considered most likely to exist in a plus minus range of 38 points above and below your current rating.
Your rating will not adjust by 100 points in 1 game if you play.
The new player you cited might have an RD of 200. His rating might move 100 points after a game. Yours won't.
You didn't name the other systems you have heard about so I cannot comment on them, except to say that such systems sound like your moves would be judged against computer recommendations like the CAPS system introduced here two years ago with a lot of fanfare.
It wasn't well received because the scores from one game to the next would fluctuate wildly. Perhaps it will improve with further refinement.
