Line Ups Recap

Sun 8 February 2009 Leave a comment Go to comments

I am currently using entirely objective criteria to determine the line ups for regular sessions.  Once the 10 players for a session are finalised, I list them according to their rankings, and divide them into teams as follows:

  • Team A – 1st, 4th, 5th, 8th, 9th
  • Team B- 2nd, 3rd, 6th, 7th, 10th

The use of rankings to determine line ups stemmed from Bret’s suggestion on 6 August 2008 and was discussed in some detail when first implemented in October 2008.

The rankings themselves are based on the following formula:

((P + P/WK + (W1 x 2) + W2 – L)/(P+S/WK)) + (P/(S x 2))
where:
• P is the number of games played by the participant in the current attendance period (both ranked and unranked games).
• WK is the total number of weeks to date in the current attendance period.
• W1 is the number of ranked games won by the participant in the current attendance period.
• W2 is the number of unranked games won by the participant in the current attendance period.
• L is the number of the participant’s losses in ranked games in the current attendance period.
• S is the total number of sessions played to date in the current attendance period.
• The current attendance period comprises the current and preceding quarters.

It’s essentially a win-loss ratio, weighted in favour of those who play more games.

Like I’ve said, games are unranked in that the line ups are not based on the rankings. The results of unranked games still go into the rankings – it’s just that they count for less.

I hope this clears up any remaining confusion.

For a while, I considered using some amount of variability to try to achieve more even line ups, for example, swapping the 5th to 8th ranked players or the 9th and 10th ranked players as follows:

  • Team A – …, 6th, 7th, …
  • Team B- …, 5th, 8th, …
  • Team A – …, 10th.
  • Team B- …, 9th.

However, it introduced greater subjectivity into the line ups, which ultimately, I have no interest in continuing.

We’ve also tried having “captains” selecting teams, but apart from introducing greater complexity in terms of choosing captains and a system for them to select their teams before the session, it also introduces a high degree of subjectivity into the line ups.  Further, apart from Tom, no one else chosen as captain appeared to have much interest in selecting their teams.

It’s simpler and more transparent to stick with the use of entirely objective criteria, that is, the rankings, to determine line ups.

If there is a new player, he will be the 7th ranked by default.  If there are two new players, they will be the 7th and 8th ranked by default.  If there 3 or more new players, the whole session will be unranked.

I’m sticking quite strictly to the use of rankings, which is why line ups are only finalised in the late afternoon of the session itself (to take into account any late withdrawals).

It is of course open to the 10 who are playing a session to agree for the two sides to swap players.   Like I said before, I’m not looking to dictate or control what happens on the pitch or during the game.   Ultimately, it’s for the 10 who are playing to decide how the game should be played.

Apart from not checking the line ups before the session, another reason to bring both colours for each session is that it leaves open the option of swapping players, whether to make the sides more even, or in the event of injury or one side being a player short.  A reminder that the colours are based on the day of the week:

  • Monday: Black, Red.
  • Tuesday: Red, White.
  • Wednesday: White, Black.
  • Thursday: Black, Red.

The colours for each session are also shown on the “Current Schedule” page.

    I have limited capacity to accommodate requests to put a player and his introducer on the same side. I’ll only do it if it can be achieved by swapping the 5th to 8th ranked players or the 9th and 10th ranked players as described above. If both players are within the 1st to 4th or 5th to 8th ranked, then it won’t be possible.

    Please put any such request up on the blog. Thanks.

    From next week, after listing the players in order of their rankings, the line ups for for a 5 v 5 will be determined in the following order:

    • Team A – 1st, 4th, 6th, 7th, 10th
    • Team B- 2nd, 3rd, 5th, 8th, 9th

    For a 4 v 4, I’ll stick with:

    • Team A – 1st, 4th, 5th, 8th
    • Team B- 2nd, 3rd, 6th, 7th

    The aim is to have the highest and lowest ranked players in the same team.

    For a 6 v 6 at Sports Planet, the line ups will be:

    • Team A – 1st, 4th, 5th, 8th, 9th, 12th
    • Team B- 2nd, 3rd, 6th, 7th, 10th, 11th

    Again, the aim is to have the highest and lowest ranked players in the same team.

    Since December last year, I have been treating unranked players joining us for the first time as the seventh player.

    From next week onwards, I will give them a notional ranking equivalent to the seventieth percentile of the entire ranking list.

    In the above formula, a player gets 1 point for each game played, and further, 2 points for a ranked win, 1 point for an unranked win, 0 points for a draw or unranked loss, and -1 points for a ranked loss.

    It is simpler to say 3 points for a ranked win, 2 points for an unranked win, 1 point for a draw or unranked loss, and 0 points for a ranked loss, and I’ll stick with that from now on.
