THE GPI FORMULA FAQs Q How is my overall GPI score calculated? A For each qualifying tournament a score is assigned by multiplying the Buy-in Factor, Q Won’t HR tournaments get an unfair amount of points due to the buy-in factor? AGING PERIOD PERIOD 1 PERIOD 2 PERIOD 3 PERIOD 4 PERIOD 5 PERIOD 6 LENGTH OF TIME FROM LESS THAN TOURNAMENT START 0.5 YEAR SCORES INCLUDED 5 0.5 YEAR TO 1 YEAR 5 1 YEAR TO 1.5 YEARS 4 1.5 YEARS TO 2 YEARS 4 2 YEARS TO 2.5 YEARS 4 2.5 YEARS TO 3 YEARS 4 and my PoY score? The differences between the GPI and PoY scores are as follows: The PoY does not take into account the Aging Factor. The PoY allows thirteen scores in the latter half. Tournaments must have occurred in the past 12 months to qualify for inclusion in your PoY score. A Q Why is a logarithmic function used to calculate the Buy-in Factor? It does so because the incremental increase in the skill set of the field diminishes as the buy-in amount increases. For example, the percentage increase in buy-in between a $1500 and $2000 event is much greater than the increase between a $19,500 and a $20,000 buy-in. The increase in the Buy-in Factor reflects this. You can see this effect when looking at the chart below containing sample Buy-in Factors. A SAMPLE BUY IN FACTORS Q I see players at the top of the rankings that play HR tournaments regularly – isn’t a lot of their score coming from these events? Most of the points for the GPI Top 20 come from buy-ins of $1,100 or less. Most players have a mix of points from smaller and larger tourmaments. A Q Over time my GPI score for a given tournament gets smaller, why is that? This is due to the Aging Factor, a multiplier that gives more points to tournaments played recently. Each Aging Period has a different multiplier which decreases as the Aging Period becomes less recent. The chart below shows the GPI scores over time for winning a $1,000 buy-in tournament with a field of 2,500 players. A GPI SCORES OVER TIME 250 200 4 BUY-IN FACTOR THE GPI FORMULA Q What is the difference between my GPI score No. The GPI formula was designed to avoid that. There are a couple of different ways it does this: The use of the logarithmic function when calculating the Buy-in Factor. A cap is placed on the buy-in at $20k. Any buy-in greater than $20k is treated as if the buy-in was only $20k. (Also, all tournaments with a buy-in smaller than $400 are treated as if the buy-in was $400.) A GPI SCORE Finishing Factor, and Aging Factor. That score is then multiplied by ten to give it a larger scale. Each of those scores falls into one of six time periods, called GPI Aging Periods. The sum of the top scores in each Aging Period makes up the total GPI score. 150 100 50 3 0 2 PERIOD 1 PERIOD 2 PERIOD 3 PERIOD 4 PERIOD 5 PERIOD 6 AGING PERIOD 1 Q Won’t the winner of the WSOP Main Event BUY-IN 18,500 20,000 17,000 15,500 14,000 12,500 9500 11,000 8000 6500 3500 5000 500 2000 0 get an extremely high score due to the field size in calculating the Finishing Factor? No. A cap of 2,700 players is placed on the field size. Any tournament with a field size larger than 2,700 players will be treated as if the field was 2,700.
