  <p>Here is all of the possible values in both of the columns.</p>
  
  <p>For RSUPP_NUM:</p>

  <p>Does "E" mean experienced, and "P" mean provisional?</p>
  
  <p>Does the 1-12 value mean it correspond to months? Does it mean the rating a person has corresponding to that month's value? </p>

Title: USCF player question
ThreadText: # USCF player question
  
  (Asked by: username_0 on 2016-02-13)
  
  I was looking at the list of uscf players (as anyone can through WinTD) and two columns in a dataset, downloadable through the program, are titled RSUPP\_NUM, R\_PLR\_TYP.
  
  Does anyone have any idea what these columns mean? I see that these are short for Rating Supplement Number and Rating Player Type, but am unsure of why this is there.
  
  Here's a screenshot of what the data looks like.
  
  [![USCF chess](https://i.sstatic.net/1d4ow.jpg)](https://i.sstatic.net/1d4ow.jpg)
  
  Here is all of the possible values in both of the columns.
  
  For RSUPP\_NUM:
  
  [![enter image description here](https://i.sstatic.net/hT7qT.jpg)](https://i.sstatic.net/hT7qT.jpg)
  
  For R\_PLR\_TYPE:
  
  [![enter image description here](https://i.sstatic.net/TD1R8.jpg)](https://i.sstatic.net/TD1R8.jpg)
  
  Does "E" mean experienced, and "P" mean provisional?
  
  Does the 1-12 value mean it correspond to months? Does it mean the rating a person has corresponding to that month's value?

  As can be verified by looking at player information on <http://uschess.org>, RSUPP\_YR and RSUPP\_NUM are the year and month of the latest supplement with a rating for that player (which is in the R\_LPB\_RAT columns). If you looked up a sample player who has a P in R\_PLR\_TYP, it wouldn't be hard to confirm whether that means that the rating is provisional.
