For any event with a buy-in larger than the buy-in cap, the buy-in cap is used to calculate the score rather than the actual buy-in amount. The GPI seeks to capture this concept of diminishing returns by using a logarithmic function.Ī buy-in cap is applied at roughly the 99th percentile of qualifying events to ensure extremely high buy-in events do not skew the overall GPI score. The percentage increase in buy-in between a $1500 and $2000 event is much greater than the increase between a $19,000 and a $19,500 buy-in. The GPI takes into account the concept of diminishing returns on the buy-in to an event. Larger buy-in events presume that the difficulty of the field is greater because more elite players enter higher buy-in events. This factor addresses the concept of relative difficulty for the event. The next factor used in creating an individual event score is based on the buy-in for the event relative to the baseline buy-in for events, $1000 USD, while still allowing events with buy-ins as low as $1 USD. The field size cap for 2014 is set at 2,700., Buy-in factor Administration to determine the cap on field size is performed one time per year. For any event with a field size larger than the field size cap, the field size cap is used to calculate the score rather than the actual field size number. The lower the number of entrants for an event, the larger the percentage change in base score between a first and second place finish, or any other places in comparison to each other.Ī field size cap is applied at roughly the 99th percentile of qualifying events to ensure that events with extremely large field sizes do not skew the overall GPI score. The higher the number of entrants in an event, the smaller the percentage change between the base scores for, as an example, a first and second place finish. This means that the relative percentage change in base finishing score between any two places is different depending on number of entrants. The base finishing score is calculated as the percentage of the field that is bested by a given player. The GPI finishing score is expressed as the finishing position relative to field size of the tournament. The GPI uniquely takes into account finishing place relative to total field size for an event. The GPI limits results to five (5) results per half-year time period for the most recent 18 months and four (4) results per half-year period for the prior 18 months for a maximum total of 27 scores per 36 month aggregation period. Aging factor refers to the weighting of results by their recency, where more recent results are weighted more heavily than past results. Buy-in refers to the relative amount of the event buy-in to the baseline buy-in of $1000 USD (events with buy-in below $1000 are still compared relative to a baseline of $1000). Finishing percentage refers to the percentage of the starting field a player bests in his or her finish. The score for a given event is derived from a combination of their finishing place percentage, buy-in and aging factor. Each player’s individual GPI score is an aggregate of scores in events over the previous 36 month period, measured from the day the GPI is calculated. Players are ranked according to their finishing scores in qualifying tournaments. Qualifying tournaments are events with 32 or more players and a buy-in of $1 USD (or other currency equivalent) or higher that are open to the public, and are not specialty or selected audience events such as charity, seniors, doubles, satellite, women, team, employee, executive and CEO events. If a player cashes multiple times in the same tournament their score will be based on their highest finishing position. ![]() Players may only receive one score per tournament. Typically the top 10% to 20% of the participants in an event finish in a cash position. A cash position is any position where the player receives a portion of the total prize for their performance in an event (all references to buy-in are inclusive of entry fees). Players are ranked weekly based on their performance by finishing in cash positions in qualifying tournaments occurring over the previous 36 month period.
