| Topic: How the IFP Point System Works |
| ||
|
Posted onto the Foosballboard.com page. http://foosballboard.net/phpBB/viewtopic.php?t=8379 is the link to the thread that this post is from. Ahmad Shadman posted this, he is in charge of the Points Commitee for IFP - which is essentially the only major point system in North America now. ------------------------------------------------ HOFC is around the corner and it is time for an update on the point system. First, we would like to thank Mary for the incredible number of hours she has put into this effort. We also would like to thank Pat Ryan (our USTSF president) who has supported this effort, and the many State Directors and Regional TDs who have taken the time to review the 2011 reset rankings and provided feedback. I suspect that over 95% of these recommendations were adopted so clearly we needed and continue to need a lot of help. I personally would also like to thank David Radack, Kent Ross, and Will Stranks who despite their continued preference for adopting Elo agreed to review many iterations of the new point system and offered important recommendations on ways to improve the system. I know there will be those that will question not using Elo, and I will be happy to discuss that later. However, for the next few days I would like to concentrate on answering questions regarding this system and making sure that players attending HOFC have a clear understanding. Please note that there is still time for anyone coming to HOFC to contact the committee regarding an adjustment to their ranking. Also note that until the appropriate programming has been put in place in Mary’s software to handle separate doubles and singles points, we will only have one set of points. The class ranking for each player remains in place for the full calendar year regardless of point status during the year unless the committee decides to bump a player. For example, there were two Amateur players who were bumped by the committee to Expert after the TKO. The point system will be updated for all IFP and non IFP events with a prize pool larger than $2,500. Clearly, it will be up to the TDs for the non IFP events to provide this information in a format that can be used. This is going to be very simple. For each event, we will need a complete list of player names, state, and final placement within the event. These results must be submitted immediately after the event so points can be updated prior to the next event on the calendar. In the long run (before the end of 2011), a programming team will put in place the necessary interface to make this an automatic process. So here it is: http://66.116.186.14/foos/NewPointSystem.pdf |

The New Point System - The point system will be applied to seeded singles and doubles events. The idea is simple. Players finishing below their seeding will lose points. Players finishing above their seeding will gain points. Additionally, players finishing in the money will earn bonus points. How does it work? Every player registered for an event contributes 2% of their points into a pool for that event. The total becomes the Total Contributed Points (TCP). The TCP will measure the size and the strength of an event. For example, the 2011 TKO Amateur Singles event had a TCP of 498 points (combined sum of the 2% contributions of the 29 players in the event). The 2011 TKO Pro Singles event with 67 players had a TCP of 2,728 making a natural distinction between the two events. The contribution charge will vary based on the size of the tournament (1% for tournaments $2,500-$10,000, 2% for tournaments $10,001 to $50,000, and 4% for tournaments paying more than $50,000). So how does a player lose points? Let us say Player A with 2,000 points enters a singles event where he is seeded #20. He contributes 40 points (2% of his points) to the TCP and is expected to finish 17th to 24th. If he finishes where he is supposed to, he gets no point adjustment. For every round (up to 10 rounds) that he exits before his expected exit round, he loses 10% of his 40 points. So if he finishes 25th to 32nd he loses 4 points. If he finishes 33rd to 48th he loses 8 points, and so on. |

And how can a player gain points? Player B with 1,500 points is seeded 35th and manages to finish 8th. This player has exited the event 5 rounds later than he was supposed to. He will be entitled to gain a portion of the points lost by those exiting earlier than expected. For example, at the 2011 TKO Pro Singles event, 26 of the 69 players failed to reach their seeding and lost a total of 407 points. These 407 points were distributed among the 24 players who finished above their seeding based on the number of rounds they went beyond their seeding. And what about rewarding the winners? Bonus points will be awarded to those finishing in the money in order to keep the top players in each rank on a steady march towards the next higher rank. The bonus points will be assigned based on the following table, as a percentage of the TCP for the event. For example, at the 2011 TKO Pro singles event with a TCP of 2,728 points, 436 points (16% of the TCP) was distributed among the top 6 places (92 point to 1st, 83 points to 2nd, 74 points to 3rd, 67 point to 4th, and 60 points to 5th and 6th place finishers). |

That's it. Hope you all enjoy the new point system that is a vast improvement by any standard I think. Any other points systems have either suffered from not enough data, no frequent updates, or poorly designed system's in general. This one at the very least will be updated after each tournament and includes all major tournaments. |

Good work on this Will, Ahmad and others. Points is a thankless task. Still thinking about what we will do and whether it is worth it. A lot of turnover of expats every year and the Chinese don't get to play in enough events for the points system to reflect reality but it would still help anyway so still considering it. Best of luck in Vegas as well everyone and if you are ever in Asia be sure to let us know. FredInShanghai |

But how does it work? |

Read the .pdf file on the foosball board, it explains it in a little greater detail. Basically you get points for placing either in the money or above your seed and loose points for placing below your seed. |

|
Will, wouldn`t you end up losing points for placing at your seed and out of the money in this system because you are paying points into the pool before you start playing? |
| ||
|
Nope - your points are refunded to you if you place in the spot that you should. You lose more points for finishing further back, and a few less for finishing closer to your seed. I have a bunch of excel files that have all the TKO and how that tournament calculated so you can see exactly how it works if you are interested. |

That`d be awesome Will |
