I got a complaint yesterday, with a suggestion to change how we deal with effect of people withdrawing. I admit I wasn’t too positive in my response, as we constantly have discussed this a lot over the years, and I have yet to see a perfect, working solution. And even if we all strive for fairness (don’t we?), fairness isn’t as objective as it should be. What seems fair for one player, seems deadly unfair for the other. My job in this is to look to the greater good, or the optimal solution. As I still have one day before I go back to work, I decided to test some scenarios. But first – I want to draw your attention to the rules and some league history. Current rules about missing games and a couple of posts on the topic.
OK – back to the current problem! If someone withdraws before playing all games, their remaining games are annulled, and the affected opponents have one counting game less. The rest of the players still have to play their 10 games. The statement was made that this was not fair for the players who have 10 games to play, and we should remove the lowest score from these players, to make them have 9 counting games also. As I needed to see the added fairness of this, I created some scenarios and tested these on a random round, where there were no withdrawals. I renamed all contestants, so that the rankings and changes would be easier to read. The names (initials A-T) were given based on original ranking in a round without withdrawals:
- Alan
- Bert
- Carl
- Doug
- Evan
- Fred
- Gina
- Heidi
- Ivor
- Jack
- Ken
- Linda
- Muriel
- Neil
- Oscar
- Polly
- Quito
- Rudi
- Selma
- Tyr
This means that a “fair” system with Polly withdrawing, should not have any effect on who is in the final at all (ranking among top 8 makes no difference for final). And likewise, if Evan withdraws, Ivor should take his place among the 8. Agreed? Of course – with the no-show practice we have, it DOES matter if you are 9th or 13th. But that is a secondary issue. We DO assume people will play in finals if they qualify.
The scenarios I tested against this was:
- Current rule applied:
- One withdrawal by player high on list (5th of 20 players)
- One withdrawal by player low list (16th of 20)
- Suggested rule applied:
- One withdrawal by player high on list (5th of 20)
- One withdrawal by player low list (16th of 20)
In all cases the player withdrew after 3 games, i.e. 7 games were annulled. The “no. 5″ player is Evan, and the “no. 16″ player is Polly before withdrawals, in all cases.
Results – current rules:
- When Evan withdraws, Ivor loses his place to Jack. Ivor was scheduled against Evan. Jack wasn’t.
- Not many changes below line (wrt. filling of open slots at final)
- 6 (of 20) players change rank with one place compared to original list. 2 players move 2 places up or down.
- When Polly withdraws, all 8 finalists keep their places.
- Ivor drops 2 places (because he lost the score of 5 he originally would have had against Polly).
- 8 players change rank with one place. One player move 2 places.
Results – suggested rules:
- When Evan withdraws, Ivor is pushed down by Jack, Ken and Muriel, as his game was annulled, while they got higher averages as their worst score were removed.
- 2 players move 1 place, while 9 move 2 places or more.
- When Polly withdraws, Gina loses her place to Jack, as he got higher average from removing worst game.
- Ivor is pushed down for same reason as above, his original win against Polly was annulled.
- 11 players move 1 place from initial ranking, 4 moves 2.

Conclusions:
Can we really draw any strong conclusions? I don’t think so. Based on this, however, I do not see there is a reason to change from what we have. I do not think current rules are without flaws, but we need something better if we should change.
My observations are:
- Current system has – in total – less effect on the ranking. As such it is presumably more fair.
- Suggested system favours those who weren’t affected directly by the withdrawal.
- Both rules affect the players closest to the line most. (Only thing to do is to secure your smiley early.)
- Any withdrawal will affect “innocent” players. So think again, both when you sign up, and if you consider withdrawing.
- If a player who is regarded stronger than you withdraws, there is an upside for you. If he is regarded weaker, you might lose an easy game.

PS.
I also understand this matter has been discussed before taking it to me, as I am “hard to get hold of”. I really hope that you do not feel it that way, I try to be available. To make it easier to get help, we got Flora Jewell to help us as CEO (Complaints and Etiquette Officer). If you do have complaints/questions/suggestions regarding “operations” she will help you swiftly. If she can’t do it there and then, she will come back ASAP or contact me for help. Your team captains should also be of great help, as they are seasoned league players.
I am still available and I am responsible for the draws, the finals and keeping this machinery going. I am on European time (SLT +9). I have a RL job, but SL is an important hobby, so I spend a lot of time here. My IMs are rarely capped, and they go straight to my email if I am not in-world. This way I can respond even if I am not in SL. Notecards also works well – if you have longer essays (i.e. bigger problems, longer solutions…). And if I do not answer when I am online, I am most likely AFK for a little while. But “…I will be back”…. suddenly.
