A Hitchhiker’s Guide To the USCF Supplement – Part 1

 

What’s rating supplement and why it matters to you?

Each month, USCF publishes the supplement rating for each active member/player, which is used in many official events or qualification for events. For example:

  • scholastic top 100 list
    • if you contact Susan Cantor at USCF and disclose your child’s birthday, then your child enters the race for the top 100 list. It’s broadcasted monthly on USCF website, based on rating and age group. There is separate ranking list for girls, although it’s not uncommon to see girl players at the top of the “Open” or overall ranking list.  Here is the link to USCF Top 100.
  • world events qualifier
  • it affects pairing on every tournaments or quads you play
    • for quads, a few rating points could push you up or down an entire quad.
    • in swiss, especially those less than 7 rounds, it could determine if how tough the tournament gets, depends on if you are the lower half or upper half of the section

Interesting things we learned from the supplement data

biggest rating jump month over month

You work hard and played a lot of tournaments. Each month, there is one thing that most chess players check is the rating increase or decrease, willing or not, it’s there. Supposed you did really well in the last month, how excited should you be about your progress? Let’s take a look at the outliers and average rating increase from the USCF database.

Some might argue at this rating level, it’s not difficult to jump rating a few hundred points higher. Let’s take a look at the mid of class B level. Many people believe 1700 is the “above-average” level. Let’s take a look the most dramatic monthly rating increase when a player’s rating is over 1700:

I saw a lot of familiar names there, some are friends or friends’ children. Seems over 100 rating point increase at master level is still possible, but I don’t want to make you feel upset by just looking at these outliers. After all, luck plays a role in any sports, including chess. Let’s look at the average.

Average Monthly Rating Changes

You see, the average is pretty much below 15 rating points per month. If your child just had much bigger increase that, you really should celebrate and be happy about it.

Another interesting from this chart is, did you notice January, March and December are the months when people got the most boost on their rating? Could it be there are lots of quality tournaments during that time? Not sure, but you can definitely give it a try. February is the worst month, maybe because there is usually less days in the month and there is no holiday hence long weekend which is usually a good time for quality tournaments.

Also, one more words, please don’t be too obsessed with rating — it goes up and down just like the stock market, but just make sure you are working hard and working smart on the right thing. I’d prefer a rating chart resemble that of a bluechip stock — it could have ups and downs but the overall trend is solid up.

Coming up:

On average,

  • how long does it take to become a class B player from a USCF rating of 1000
  • how long does it take to become a class A player
  • how long does it take to become an expert
  • how long does it take to become a national master

and much more. Stay tuned!
