USBGF Ratings and Stats: Mission and Policy

Gregg, if you're suggesting separate rating lists for open, intermediate and novice levels, I don't think that's the way to go. Other live-play ranking lists do just fine with a single list, although most likely there is a lot more mixing within each of those pools than there is the U.S. I still think it's true, though, that in them open level players tend to play other open level players and intermediates tend to play intermediates, but better players tend to have higher ratings. To my knowledge there are no intermediate players in the Danish Top 20. I can't say the same for top 70.

With regard to mixing and rating in the U.S., I think that's problematic anyway -- there are perhaps one dozen open players who travel widely, a lot more who travel much less often, very few intermediates who travel, and (I suspect) huge numbers of intermediates who only attend one tournament a year.

I suspect that in a single U.S. list, winning open players would rise to the top of the list. Perhaps the larger problem, if it is a problem, is that losing open players will tend not to be as highly ranked as winning intermediate players. But again, I think it would be very interesting to see a spreadsheet of all open and intermediate players who have attended at least one tournament, say, in the last three years and how many tournaments each of them actually attended.

How many U.S. players are there? An inquiring mind wants to know ;-

Let me note that a U.S. rating list might be made more robust by not strictly limiting the events that qualify to be rated. I mean that in side events like warm-up tournaments, doubles, and small and large jackpots there may be a lot more mixing of players of dispare skill than in the main events; that would mitigate whatever effect there may from the fact that A players play A players and B players play B players in the main tournament events.

Let me also second Christian's suggestion -- the DBgF has 20 years experience in deciding what statistics to collect, what to rate, how to rate it, how to collect it, save it, present it, and so on.
