IFPA Ratings System!

New for 2012, the IFPA is proud to announce the implementation of the IFPA Ratings System for all players. Currently the IFPA Ratings System uses an unmodified version of the Glicko rating system. Rather than focusing on head-to-head play we are using tournament finishing results as the data for the calculation. For a given player in a tournament, any player finished ahead of them is treated as a loss, and everyone they finish ahead of is treated as a win. Ties are when a player finishes in the same

position as other players. RD is limited to a range of 30 to 350 for a given player. A player's RD increases daily, with it taking about 3 years to drop out of the ratings altogether (similar to the period used for the IFPA's World Pinball Player Rankings).

Right now this rating is unofficial, and will be for all of 2012, however we have plans in the future to hopefully include the IFPA Ratings System as part of the World Pinball Player Rankings formula to help determine tournament strength. Unlike the formula for the World PInball Player Rankings which will not change during the year, the IFPA may choose to adjust the formula for the IFPA Ratings System at anytime during the year as it serves no official function at the moment.

Any feedback, questions or comments about the IFPA Ratings System is appreciated. We're excited to explore the possibilities of making the world's official player rankings system even better in the future!
