That's the LAME CLAN CHALLENGE SCORING SYSTEM, of course.
More than three years ago, Russ asked players to vote on the following question:
The current clan scoring system rewards clans for quantity of challenges played because there are no penalties for losing. Would you like to see the current system replaced and see a clan’s rating impacted by a loss?
"Yes" received 86%. Yet, no change has been made except adding a "Net" column that no one cares about. In the words of the question, the current system (i.e. the LCCSS) was to be "replaced", not augmented by another stat. So get to it, Russ.
Pendejo, I and others worked up a system three years ago. The details are in: http://www.timeforchess.com/board/showthread.php?threadid=19482&page=1
I'll repeat the salient details here:
First every clan starts with a Clan Rating of 1200.
The changes in the rating will be based on the changes of the individual players rating caused by the result of the match + a clan bonus or penalty based on who wins or loses. I will give as an example the present match between between the Contumelious Clan and the Pawn Stars.
The lineups is as follows: Frogstomp 1686 - Marko Krale 1711
TMetzler 1467 - Roseo 1424
Ravello 1304 - Headsy 1330
The player's rating would be frozen for the purposes of the allotment of clan points to the level at the start of the challenge. Thus later changes would be irrelevent: Ravello would always be considered a 1304 for the purposes of this challenge. This would avoid the chicanery of people resigning games to avoid losing clan points. The result of EACH GAME would be added to the winning player's clan's team rating and subtracted from the losing team's rating.
Example: Both clans are starting at 1200. Ravello a 1304 defeats Headsy a 1330 in their first game; using the RHP calculator Ravello clan would gain 17 points while Headsy's would lose 18. Thus, after this game the Contumelious Clan would be at 1217 and the Pawn Stars would be at 1182. Suppose Headsy wins the rematch; again the calculator would give the Pawn Stars 14 points and subtract 15 from the Contumelious Clan. The split would leave the Contumelious Clan at 1202 and the Pawn Stars at 1196 as Headsy had a slight rating advantage. This computation would be done for EVERY GAME making every player and every game important to the result.
In addition, a 10 point bonus would be added for each person in the challenge to the winning clan. Thus in our example, when the Contumelious Clan won, they would receive an additional 30 points aside from the ones awarded for the individual matchups. The Pawn Stars would lose 30 points or 1/2 that amount depending on what was decided.
Back again; as to the inevitable complaints about retroactivity, I'll repeat what I said then:
Moreover, the whole clan system is completely played out and boring as it exists now. A fresh start would add drama to the clan system; the same ole clans wouldn't have their positions locked in. Give Metallica a big gold star and let's get on to playing matches under a system that makes sense and in a wide open competition where every clan will have a shot.
Made sense then, makes sense now.
