Participation Records, Rankings & Line Ups: Third Quarter 2009

With the start of a new quarter, the results from the first quarter will be dropped from the participation records, and will not count towards the rankings.   As such, the rankings will change drastically when it is updated at the end of this week.

Around the end of the current quarter, when the number of weeks reaches 26 (end of September), instead of dropping the results in the current quarter, the participation records will continue as a rolling 26-week record – as the results for each week are added at the end of the week, the results for the earliest week in the records will be dropped.

At that stage, the participation period will be the previous 26 weeks instead of the current and preceding quarters.

I have not started the rolling 26-week record immediately as there were variations in the points system between the first and second quarters.

To accommodate a rolling 26 weeks, at the end of this week onwards, the results will appear in a single sheet in the Excel document (instead of being divided into 2 sheets, one per quarter).   However, 11-a-side games will be recorded in a separate sheet, so that we have a clearer idea who are interested in 11-a-side games.

From now on, the highest position reached will be shown for two separate periods – the first 6 months and the second 6 months.

2 and 3-pointers were introduced at the start of the second quarter to emphasize participation over competition.   We have not had any 3-pointers so far.  I’ll do away with 3-pointers.

The ranking formula can be found here.

When the places for a session are filled, line ups can be determined by either the selection method or the default method.

For the default method, the players are seeded according to their ranking.    The players have been allocated teams strictly according to one of the fixed sequences.  From now on, in exceptional cases, where the default line ups are clearly unbalanced, I might swap any pair of seeds.

As before, the two teams in a session can agree to swap players.  To allow for all of this, it is useful if everyone brings both colours for the day.

    A reminder that the Current Top 40 only shows the top 40 at the end of each week. The full listing can be downloaded as an Excel document from that page. The full listing shows the workings and includes a lot of other details.

    The Top 40 and full listing are updated on Sundays.

    It’s all for fun.

    From this week onwards, I will include the results of any Saturday or Sunday sessions in the end-of-week rankings.

    However, to allow more time for voting in the player poll, the votes for the Saturday or Sunday session will only be included the following week.

    Apart from moving 11-a-side games to a separate sheet in the Excel document, all games against other opponents will be worth a fixed 1.5 ranking points regardless of the result. Playing in such games is shown by the letter “R” (representative games) against the player’s name in the column for that game. Playing for the opposing side is not taken into account.

    The points for a 4-team mini-league tournament have been adjusted as well:

    • First – 2 points instead of 3.
    • Second – 1.67 points instead of 2.33.
    • Third – 1.33 points instead of 1.67.

      Was there a calculation error on my points? How did i end up 7 places above Imran all of a sudden? He was ahead of me last week and i think he got more points than me for the past week.

        It’s an average. He played a lot more games last week. He won one out of four games, while you won one out of two, so on average, you did twice as well as he did.

        Also, several participants in the top 20 who didn’t play as often in the second quarter as they did in the first quarter have fallen out of the top 20, which pushed you up even further.

        You can check the workings in the Excel document.

    rankings is not important to me BUT its ridiculous that i was 14 last week, then suddenly im 40 this week despite winning a regular session! And imran was my opponent n he is way above me?? Some kind of a joke?

      I dropped all results from the first quarter, so all your wins from the first quarter went out the window. You didn’t play as regularly in the second quarter for which your ratio of wins was much lower. You can check the workings in the Excel document.

      Similar consideration applies to others such as Murray, Boris and Luke, who have dropped drastically.

      This is the last time I will be dropping a whole quarter’s worth of results. From the end of this quarter onwards, it will a rolling 26-weeks, so you won’t have such drastic changes at the start of each quarter.

      Even then, you could lose position despite winning during the week. For example, if in the earliest week that is dropped, you had won three times, and in the most recent week, you only one once, you’ll have two fewer wins, so your average goes down, not up, despite winning.

      Read about other rolling ranking systems, such as FIFA World Rankings and ATP Entry Ranking to understand this better.

        Thks for your explanation, rajiv..

          You’re welcome.

          A further point to note – while FIFA World Rankings and ATP Entry Rankings are based on aggregate points accumulated over the rolling period, the FIOFAFI system is an average, more akin to ranking systems for chess and other board games such as the Elo rating system.

          For the FIFA World Rankings and the ELO rankings, there is some adjustment to cater for the differing strengths of the opposition.

          In the FIOFAFI system, line ups based on seedings is aimed at having a similar effect, without requiring other adjustments.

          The FIOFAFI system is also akin to the ATP Entry System in that certain competitions carry more points. For example, Grand Slam tournaments are worth more than other tournaments on the tour. Likewise, for FIOFAFI, a 4-team mini-league tournament carries slightly more points.

    Looking at the rankings put up on Sunday evening, the inclusion of all votes since 1 April 2009 benefitted those who earned a lot of votes in the early part of the quarter, when voter turn out was higher.

    To shift the balance in favour of those who have been playing well more recently, the rankings have been revised so that only votes over the last 4 weeks are included.

    However, as there have only been two 11-a-side games since the start of the last quarter (1 April 2009), the votes from both have been included. From now on, only the votes from the last two 11-a-side games in the current participation period will be included.

    I have expanded the listing from Top 40 to Top 50.

      As the votes now carry less weight, we have newer players or those with few games climbing the rankings much faster. To offset that, the fixed weight added to the denominator has been increased from 1.5 to 2.

    I’ve corrected some errors in the participation records, which affected the rankings.

    For representative games, the player poll will be limited to those scheduled to play for FIOFAFI, even if our opponents include FIOFAFI participants, or players scheduled to represent FIOFAFI end up playing for our opponents.

    This is how it’s been for the last 3 representative games:

    11-a-side game on 21 February 2009.
    11-a-side game on 25 April 2009.
    6-a-side game on 6 June 2009.

    As was the case last week, the votes from games and sessions over the weekend will not be included until the following weekend’s “Weekly Round-Up”.

    For the selection method of deciding line ups, any two regulars can use any method to choose their teams, provided that the two selecting their teams agree on the method and are not on the same team.
