  • CFC ratings database: some analysis for ratings & activity

    I have managed to obtain a copy of the CFC ratings database (as of Sept. 2010). Work done on this is posted at: http://victoriachess.com/cfc/ .

    Work is ongoing but so far, the site has a utility to query for the top rating list for any given date where that list includes only active players [as opposed to only CFC members and those who may or may not be active as on the CFC site]. [I define active as played in the previous 12 months]. [Cavaet - regional lists are determined by the current listed province of the player, not their historical residence if they moved].

    Looking at trends in the ratings of the nth ranked player gives conclusions similar to those in a previous thread based on the analysis of specific players' ratings. http://www.chesstalk.info/forum/showthread.php?t=3382 i.e. there has been some inflation over the last few years and it is to some extent regionally based.

    The data so far also includes some activity numbers. The graphs are shown below and they aren't happy graphs.....

    If I am reading your graphs properly, the number of tournament games played went up slightly across Canada and the number of active players went down everywhere except Alberta and BC.

    What is the criteria for deciding who is an active player?

      This is interesting... Any chance of a graph for Alberta?

          I'd like to know some definitions.

          Ontario has about 500 ordinary adult members, and about 500 juniors, honouraries, life members, etc. How did we get 2400 "active players" in 2010?

          Did each of those 1000 players play an average of 2.4 events? Is that the calculation?

          Maybe I need more coffee.

            Great question John. :)

            I am guessing that the 2400 Ontario players are including all the membership type "b" players. These are all the kids in the "junior only" tournaments we rate where the kids are not required to buy memberships. Only a guess?

            Great work Roger. Roger has asked if I have any queries he can run for me, and I sure do.

            Roger, I'll email you some questions over the weekend.

            Thanks for doing this analysis. It will be a great help in understanding our members needs. :D

              Aha, I drank coffee, followed the link, http://victoriachess.com/cfc/ and found the answer:

              "Note that the number of active players is much higher than the actual numbers of CFC members (by a factor of 2 or more) This is largely due to the presence of junior rated tournaments for which CFC membership is not required. (these are usually players with ratings below 1000). "

              However, I have another question. The membership numbers for the CFC are presumable PAID memberships... they don't include the junior hordes, right? But those unpaid junior "non-members" each has a membership number, and appears on the database, indistinguishable from a paid member.

              I wonder if the CFC membership stats could have a column for the junior non-members.

                They have a rating for me in the current database. I haven't played a CFC rated event since around the mid to late 1970's. I'm not a CFC member.

                Maybe if someone is undecided on joining they tell the person Gary Ruben is a player to seal the deal. :)

                  The CFC database is of all players, active or not. Once rated, always rated.

                  Roger's stats are for ACTIVE players.

                    And, I believe when you lookup the rating, it shows the CFC Expiry date...
                    (for you: 2007/5/1) so you were a CFC member only 3 years ago or so.

                      That's a letdown. I thought they kept me for my star power. :)

                      I am an active player, though. Just not in CFC rated events.

                        Re: CFC ratings database: some analysis for ratings & activity

                        I defined active as having played at least 1 game (regular rated) in the 12 months previous to the date queried.

                        In answer to some of the other posts, yes, 4000 active players versus 1800 or actual members (some of whom are dead or otherwise not active :-) ) is a result largely of junior events with players only requiring to pay $0.50 rating fee. This is not done in all regions so interregional comparison is a bit tricky. If you look at the top rating list at the link provided (or just go here http://victoriachess.com/cfc/ranking...9&province=CAN) the full rating list is printed out and you can see that ~2000 of those players are rated less than 1100.

                        Three comments to that issue:
                        1) I plan to look at rating distributions and activity versus rating which will yield more direct comparisons. Actually, I didn't plan to do the present activity numbers until later but they fell out more or less automatically from the present project (looking at the ratings of the nth ranked player) and were pretty disturbing (who knew 90% of Saskatchewan dissappeared?) so I published them.

                        2) Those who argue that the only model for the CFC is a annual membership model are overlooking that de facto, pay per tournament is how more than half the activity rated is done.

                        3) If ~half the rating activity is handled at $0.50 per player with no membership fee, it had a) better be true that the rating costs are truely covered b) I suspect the governers are not truely aware of the discrepancy of a large portion of CFC office work being related to at best cost recovery for juniors versus the substantially higher costs for adult membership and play.

                          That's correct. I paid a membership for the printed magazine. The magazine I'd been getting was no longer published. As luck would have it, the CFC also stopped the printed magazine.

                          If there is any magazine you don't like and wish would stop publishing, send name and address. I'll sign up and see if I can keep my streak alive.

                          I didn't play any rated games. Did you know they charge entry fees here in Canada? Who'd have guessed?

                            CMA charges $0.40 rating fee, and Tom O'Donnell has (or had?) a standing offer to enter CFC tournaments for $1 per player. I believe, therefore, that the adult rating fee of $3 is at least 3x the cost of entering the crosstables.

                            Subject for possible discussion: abandon membership fees completely, and just charge rating fees. It would put the CFC emphasis where it belongs, getting people to play chess.

                              Interesting graphs, and troubling. I think explanations of the decrease in active players might be among the following:

                              1. When the CFC printed magazine was eliminated many felt that joining was no longer worthwhile especially when there are alternative rating services (like CXR) which do the rating job for a fraction of the price ($8/player/per year with no game limit).

                              2. There are alternative venues for play. Like the Internet. Like postal chess. Like playing against a computer...

                              3. I personally find some of the tournament layouts less attractive than I did when I was younger. In particular, I no longer want to spend an entire weekend playing chess. I would much rather play a game a week or a tournament where all the games were on a single day. Many children (and their parents ;-) would prefer one-day events. Some tournaments have started having a game on Friday evening, then two games on Saturday and two on Sunday. For locals this might be fine but if you have to pay for accommodation it is more expensive and wipes out three days.

                              4. We are failing to attract half the population. Girls play but after puberty they largely vanish. I have had many discussions about why this might be and how to alter it but wisdom remains elusive.
