WPPR formula change for 2013!
As the landscape of competitive pinball has broadened, the IFPA is constantly investigating ways to make the World Pinball Player Rankings more accurate for how we rank players across the globe. This latest change to the formula has to do with how we calculate the first place value of a tournament. We're now using two metrics to determine the strength of each tournament, including the WPPR rank of the players in the field, along with the IFPA Rating of players in the field. The distribution of WPPR points for each tournament remains the same as it has been since 2009. For more details on these changes, check them out HERE.
A reminder that for IFPA10 qualifying and seeding purposes, we are still using the previous WPPR formula that was in place for 2012. While past results have changed, these new values will only be used for IFPA11 qualifying purposes going forward.
We also wanted to answer some common questions we get every time we change the WPPR formula:
Q: Why did my WPPR point total change?
A: This new formula recalculates all tournament values since the beginning of time, so the actual WPPR points you've earned at the events you've played are now different compared to the prior calculation.
Q: Why did my RANK change, and even though my WPPR points increased, my WPPR rank decreased?
A: With the new formula impacting values of all IFPA endorsed tournaments across the globe, it is possible that the increase you saw in your WPPR point total may have been less than the increase of other players ranked around you.
Q: Why are the value of old results changed, and not just new results?
A: Anytime we make a change to the formula we make that change retroactively for all of time. It's important for us to use the data in the past to gauge the accuracy of any proposed formula changes, and if we do find a successful simulation, we want to incorporate that for past results to make for a more accurate ranking system.
Q: What is the new formula?
A: The new formula is available in detail HERE. Also, each tournament results page now shows the breakdown of where the increase in value comes from.
This system is much better than the old one. When you travel everywhere in the world to compete and you are very involved with competition, it is a thing that I ve been waiting for so long. Players that only make local tournaments are less well trated… We must keep in mind that if you are a very good player, you must have the cash to copmpete/or sponsors…
Congrats josh and Zach, you make the pinball live and rise !
