Another sneak peek into what’s currently being talked about and proposed among IFPA leadership. As always, everything is subject to change prior to the end of the year.
Since the first World Pinball Player Rankings were posted back in February 2006, there have been complaints about the fairness of trying to compare players from around the globe where the access and opportunity to compete in IFPA sanctioned events vary so greatly.
WPPR v6.0 is focused on trying to answer a systemic problem regarding the advantages of access and privilege that certain players have at their disposal, giving themselves more opportunities to compete in IFPA sanctioned events and earn WPPR points towards their ranking at a level that is above and beyond their peers. There’s privilege when it comes to players that live close to more opportunities, and privilege when it comes to players that can afford to travel and create those opportunities for themselves. Ultimately this leads to situations where the accuracy of players we’re attempting to rank is flawed due to the inconsistent level of opportunities some may have over others.
Starting in 2024 we will be splitting the World Pinball Player Rankings into two lists.
Players ranked 1-1000 will be listed on the WPPR-PRO rankings.
Players ranked 1001+ will be listed on the WPPR-AM rankings.
The WPPR-PRO rankings will include this v6.0 adjustment, while the WPPR-AM rankings will receive no adjustment.
How will WPPR v6.0 work?
We will be calculating what we consider to be a reasonable amount of play that is acceptable for a top 1000 player. Players will continue to be allowed to play as much as they would like, however players that play in excess of this reasonable amount will see an adjustment made to their total WPPR points earned towards their world ranking.
WPPR v6.0 is an attempt at measuring to what extent your Top 20 card (or likely your Top 15 card as that’s the current plan) is a representative sample of all your comp results over the past 3 years.
To the extent that it is representative, your relative rank will go up.
To the extent that it is not representative, your relative rank will go down.
The WPPR v6.0 calculation process:
STEP 1 → Calculating the “WPPRtunity” metric
We will be incorporating a player’s Efficiency Percentage to help define what we’re calling the “WPPRtunity” metric. If a player has an Eff% of 20% and a WPPR point total of 200 WPPR’s making up their top 15 resume, we calculate this WPPRtunity metric at 1000 WPPR’s (WPPR’s / Eff%).
STEP 2 → Defining what a reasonable level of “WPPRtunity” is for players in the top 1000
We will be calculating this WPPRtunity metric for every player in the top 1000, finding an average across those top 1000 players. This average will be where the line is drawn with respect to what we consider a reasonable level of access and opportunity for players to compete.
STEP 3 → Calculate the percent of excess play over average for anyone in the top 1000 that would be subject to adjustment
If the average WPPRtunity metric is 1000 and my WPPRtunity metric is 2000, then 50% of my WPPR’s would be subject to this adjustment.
STEP 4 → Calculate the adjustment for anyone that has a WPPRtunity value that is higher than average.
The adjustment is calculated by this excessive play being awarded at the Eff% value of the player rather than at full value. For example: if I have 500 WPPR’s on my card, and my excess play value is 50%, and my Eff% is 20%, there would be an 80% reduction of 50% of my WPPR point total.
Instead of 500 WPPR’s under this old formula, there would be an adjustment of 200 WPPR’s based on this excess play. (500*50%*80%)
There is a sample worksheet showing this WPPR v6.0 calculation here:
Some things to note:
- This worksheet is a homebrew version of this adjustment that I’m calculating based on the current WPPR rankings. The plan is for this adjustment to be integrated into the rebuild after every event so we can use this WPPR v6.0 rank value in the formula used to calculate the value of each event. The homebrew version uses a player’s top 20 resume, not top 15 resume. We have a simulation privately running on our website that is actually tracking this correctly and have confirmed the results are ‘similar enough’ to the worksheet.
- The simulation we are currently tracking has the adjustment reducing a player’s Top 20 card back down to the Top 15 results (it was previously Top 15 until WPPR v5.0 was launched).
- Efficiency % stat before people ask = WPPR’s earned/ WPPR’s available for all active events on your resume (not just the events on your top 20 card)
- This change would be retroactive with a starting date of 1/1/22 once it’s implemented on 1/1/24.
