Update: Monday 5 September
After further review upon implementation of the changes made to the World Curling Team Ranking System, it was determined that additional differentiation was necessary for events. Therefore the event Strength of Field Multiplier will now be rounded down to the closest .5 interval. These changes will retroactively be adjusted for all events in the 2022–2023 season.
The World Curling Team Ranking System working group recently reviewed the current criteria of the points list.
The group agrees that the current ranking list provides an accurate snapshot of the top curling teams. Throughout the season, there is some fluctuation, depending on the timing of early championships, but overall, it functions for its intended purpose of ranking teams.
There are concerns regarding points earned in events late in the curling season (World Championships, Players Championship) start to be removed from the teams ranking by October, therefore the value of the points is only kept for five months, compared to a major cashspiel or early season slam, that occurs in September / October of a curling season where the points carry their full value for a calendar year.
The monthly point decrease from the prior year was instituted to mitigate this issue to a certain extent but further changes will be proposed for this season
Changes – Strength of Field Multiplier Calculations
- Top international events (Olympic Games, World Championships, Grand Slam of Curling events) should have a set strength of field multiplier, regardless of teams that gained entry
- This ensures that the highest profile events for the sport, also bring the most World Ranking Points
- National Championships from all Member Associations and Regional Championships (European & Pan Continental Championships) will continue to use the Strength of Field Multiplier calculation, keeping a revamped importance multiplier, with no defined point totals. This multiplier will be capped at 9.0
- This ensures that there is an accurate point totals amongst all National Championships as the relative strength of fields is so vast among all World Curling Federation Member Associations
- Tour Cashspiels should have a maximum Strength of Field Multiplier where they cannot exceed a top value.
- This ensures that early season events where top teams are all attending in order to get games in, do not artificially increase the value of the event to the same status as a World Championship or Grand Slam
- Tour Cashspiels would have their Strength of Field Multiplier calculated before the event begins and rounded down. For example, if Strength of Field Multiplier is calculated at 4.25, then it would be a 4.0 Strength of Field Multiplier event; 5.76 would be a 5.0 Strength of Field Multiplier event, etc.
- The benefits of complete accuracy to two decimal places is sacrificed to create more certainty and predictability for teams when making schedules and planning seasons. It was decided that the relative difference between a spiel with a 4.25 and 4.80 multiplier is not large enough to sacrifice the certainty for teams
- Tour Cashspiels will also be compared year over year where they will maintain a minimum level. For instance, if Tour Event A was a 5.0 Strength of Field Multiplier in year 1, the following year the Strength of Field Multiplier can only fall to a 4.0 and can only rise to a 6.0 Strength of Field Multiplier
- The ability to only climb or fall 1 Strength of Field Multiplier point in a year creates certainty for teams making their schedules as they will know when choosing an event the minimum that they will be playing for, and also will not be surprised to miss an event that climbs excessively high
- 2022–2023 season will be the first year to set Strength of Field Multiplier baselines for next season
- Purse factor will be removed from all calculations
- We also noted that certain Strength of Field Multiplier decisions made in the past were done to attempt to incentivise events to increase purses to add points which has not been the case year over year
All other calculations will remain the same.
Calculations for set point events
|Strength of Field — Set Point Events for 2022–2023 Season|
|GSOC — Players Championship||10.0|
|GSOC — Masters, National, Open||9.0|
|GSOC — Tour Challenge & Champions Cup||8.0|
|Strength of Field — Tour Cashspiels for 2022–2023 Season|
|Tour Cashpiels – Maximum||7.0|
|Importance factor increase for Special Event / Playdowns|
|Nationals||65% to a maximum of 9.0|
|Europeans & Pan Continental||65% to a maximum of 9.0|
|Play-off placing base points|
|3rd / 4th (if no bronze determined)||4.25|
|5th / 8th||3.00|
|If bronze determined:|
Changes — Roll-out of maximum events counting and reduction of prior year points
With the upheaval of team rosters following the end of the 2022 quadrennial, a true rolling system is unable to be achieved this year. Player by player 52-week rolling could be achieved but will make the system calculations exponentially harder to understand for both teams and users of the list, without significantly increasing the accuracy.
- The roll out calendar of maximum number of events that can count and the concurring reduction of prior year points will be done to attempt to mimic as best possible the “8 best events” for a team
- For example if Team A starts 2022–2023 with 240 points from their new revamped team (prior year best 8 events). The “team” earned, on average, 30 points per counting event (240pts / 8events)
- Each event is approximately 12.5% of their total points (1/8th)
- Therefore, each time during the season that a counting event slot is opened, the prior year percentage will be removed in corresponding 12.5% intervals
- Example: 4 events counting = 4*12.5% = 50% of prior year points removed
For greater simplification the calendar of maximum number of events counting from the 2022–2023 season and the percentage of prior year points is as follows:
- August 1, 2022 = 0 events allowed from current season & 100% of prior year points
- August 2, 2022 to October 4, 2022 = 2 events allowed from current season & 75% of prior year points
- October 5, 2022 to October 30, 2022 = 3 events allowed from current season & 62.5% of prior year points
- November 1, 2022 to December 6, 2022 = 4 events allowed from current season & 50% of prior year points
- December 7, 2022 to January 3, 2023 = 5 events allowed from current season & 37.5% of prior year points
- January 4, 2023 to January 31, 2023 = 6 events allowed from current season & 25% of prior year points
- February 1, 2023 to February 28, 2023 = 7 events allowed from current season & 12.5% of prior year points
- March 1, 2023 to end of season = 8 events allowed from current season & 0% of prior year points
Changes to special events allowed
Note that single elimination tournaments, will be added to the allowed event structure, as long as the event continues to meet all other requirements (8 or 10 ends, 5 rock Free Guard Zone)
Only 25% of teams in a single elimination can earn placing base points (8 team single elimination = 2 teams; 16 team single elimination = 4 teams)
The strength of field multiplier will be reduced by 25% once calculated.
Changes to Five-Player team end of year calculations
To provide teams wishing to create a five-player team, greater flexibility to award end of year points for the 2023–2024 season, teams will be allowed to mutually declare their breakdown based on their on-ice realities and team formations. Teams must declare by 1 February 2023 their intentions for their end of year point allocations to each player under the following options (all calculating to 100% of the teams points):
Full Five-Player rotation
- each team member retains 20% of the teams total points
- 20% / 20% / 20% / 20% / 20%
Front end rotation
- Skip and Third each retain 25% of the teams points and the three rotation front end players retain 16.67% each of the teams total points
- 25% / 25% / 16.67% / 16.67% / 16.67%
One player only rotation
- Three players each retain 25% of the teams points and the two rotation players retain 12.5% each of the teams total points
- 25% / 25% / 25% / 12.5% / 12.5%
Majority Four-Player team
- Two team members each retain 25% of the teams total points, two team members each retain 20% of the teams total and the fifth player receives 10% of the teams points
- 25% / 25% / 20% / 20% / 10%
Skip set and remaining team rotation
- Skip retains 25% of the teams total points, four team members split the remaining 75% of the teams points
- 25% / 18.75% / 18.75% / 18.75% / 18.75%
These options will be included in your team registration and the World Curling Team Ranking System committee will follow up with your team to ensure declarations of intention are made.
