its still 300 games aww-rats which is quite an achievement. they had for a short time the Life master norm thing that was totally absurd. requiring 3 2200 performances in 5 round events. So some experts figured out they can create small hand picked events with 1900 ish players and gain their norms with a perfect score. It might be hard to do this in an open event but if you play the same people you can nail them down opening wise and create 5 or 6 events and bam theres your rating floor and NM title . you also didnt have to complete the event either just get the 2200 performance.
I would hope you get your LM title I feel that 300 games at the 2200 level is a serious achievement.
USCF also has a Life Master title. There are two ways to get it. The old way is/was to have 300 games played where you started and completed a tournament at or above 2200. I was around 295 games completed when I stopped playing tournaments in 1996. Once a Life Master, your published rating will never go below 2200. Now, I notice I have the CM title because I did enough above 2000 to qualify for it. not quite certain what's needed for the new LM title, but I should at least be able to get the old LM title if I ever return to OTB play. Just need about 5 games and even if I drop the first try, I should be able to go back up sooner or later.
