WCF World Team Rankings & WCF World Team Rankings Points Structure - Summary for the 2020-21 Season

Rolling Out of Event Count:
Decreasing Importance of Previous Season:
1) Tour Cashspiels: this category represents the bulk of the events played on tour, including all events that qualify as Order of Merit sanctioned events. It will also include the Grand Slam Of Curling events outside of the four Grand Slams that meet the format requirements for Order of Merit inclusion.
2) Playdown/Special events: this category represents the following events: Provincials/Territorials, Nationals, Worlds, Europeans, Canada Cup, Olympic Trials, Olympics, the Grand Slams, and events similar to those described as per the eligibility requirements.
General rules that apply to all events:
Events must post results, which include full team rosters, draw schedule and full linescores on their own private website or through results service. This allows the results to be verifiable and have historical backup to the data.
Teams finishing in the top half of the field will receive WCF World Team Rankings/OOM points:
For events where finding the top half of the field includes teams finishing in an equal placing but leaves greater than 50% of the field receiving points the following calculations will be completed: the teams that make up the tied placings (ex: QF losers ranked 5th & 6th in 10 team field) that finish with a losing record during the round robin (ex: 2-3) would get 50% of their qualifying points and all other record would get the full points.
Points Per Win at 0.375 times Strength of Field will be apply to all other teams in each event to reflect the value of their wins. This will balance out the different between losing a C-Qualifier and Quarterfinalist based on the number of wins it takes to get to that game.
The points utilizes a SFM (Strength Of Field Multiplier) number multiplied by a base-point value to determine the number of points available for playoff teams:
^ If more playoff teams qualify than positions available to an event, or tied across base point valus, the value of points will be awarded based on the Total Base Value divided between the total playoff teams reaching quarterfinals and muliplied by the SFM, or teams will receive point-per-win values, whichever number is higher.
All events will utilize a SFM value (including all Playdown/Special events). This SFM value reflects the quality of the teams participating in the event. The SFM value will be calculated using the Order of Merit (OOM) ranking on the Tuesday prior to the event, and will reflect a cumulative total using the following system:
The cumulative SFM number, as calculated above, will then be scaled to a 24-team format. This scaled SFM value is now normalized so it does not reflect the number of teams at an event.
Example: A 32 team event with a cumulative SFM of 5.6:
5.6 * (24/32) = 4.2
The cumulative SFM number does not have a limit.
After the scaled SFM has been calculated, it will then be adjusted to reflect the number of teams playing in an event.ay
For Tour Cashspiel events, the minimum number of teams for Order of Merit inclusion is 8 and this corresponds to a minimum factor of 0.750. The adjusting factor maxes out in an event with 32 teams, at a maximum value of 1.5. For events in between this range, the following formula will determine the factor where n represents the number of teams playing:
1 + (n – 16) * 0.03125
The Playdown/Special events category will calculate this team factor slightly differently for both Playdown and Special Events. For all Playdown events: Pre-provincial qualification, Provincials/Territorial, Nationals and Worlds, there is no minimum number of teams to qualify for WCF World Team Rankings/OOM inclusion. Nationals, Worlds and Playdown events leading up to Nationals with 10 or more teams will use the factor described above (1+(n--16)*0.03125). Pre-Nationals Playdown events with less than 10 teams will use a more discounted formula:
Lastly, for all Tour Cashspiel events there will be a second factor that reflects the size of cash purse available to the players. The minimum purse requirement for Order of Merit inclusion is $300/team playing (i.e. a 24-team event must have at least $7,200 total purse). This purse factor will range in between 0.96 to 1.25 where the minimum ($300/team) represents the 0.96 factor, and the maximum ($2000+/team) represents the 1.25 factor. For purses in between this range, the following formula will determine the factor where p represents the purse value divided by the number of teams:
1 + (p – 500) * 0.00017
After the SFM has been calculated and scaled to the 24-team format it will then be multiplied by the 2 factors (number of teams and purse size) to get a final value. This final SFM value is then used in combination with the base-point structure (as shown above) to determine the number of points available. The following is an example:
A sanctioned Tour Cashspiel has 32 teams competing for a purse of $50,000. In the field of 32 teams, there are:
The cumulative SFM value using the above table is: 4.63. This value is then scaled to the 24-team format:
4.63 * (24/32) = 3.47
The first factor (number of teams) is at a maximum for a 32-team event: 1.5
The second factor (purse size) is calculated using the equation below. The value of p is ($50000/32 = 1562.5):
1 + (1562.5 – 500) * 0.00017 = 1.18
The final SFM value is then calculated by multiplying both factors to the scaled SFM value:
3.47 * 1.50 * 1.18 = 6.15
The last step is using this final SFM value in combination with the base-point structure to determine the points available:
Points per win will be available for all events in the Playdown/Special events category and for events in the Tour Cashspiel category for non-playoff teams only. These points per win will be rewarded as per:
Playdown/Special rules and calculations
All of the events in this category are still predominately SFM-based events. This additional factor was implemented based on historical significance to adjust the points available to match the importance of winning/placing in such events.
