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.
Here is all of the possible values in both of the columns.
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?
