World Team Ranking Calculations

The World Curling Team Ranking System (WCTRS) points model will determine the points awarded for all events using a combination of size, strength of field and relative importance of large events if necessary.

The WCTRS is a “one Curling season” list with teams still allowed to count their best eight events each season.

The WCTRS is a combination of a reducing importance of prior year results and the best events from each season. For further information on the WCTRS rankings can be found here.

The WCTRS ranking will allow a defined number of “maximum events” throughout the season until reaching the full eight. The following are the dates and maximum events allowable at each date:

Note that events played prior to each date of roll-out can still count towards your yearly total, however only the best number of events will count at each checkpoint. Example: Team A plays three events prior to 1 October 2022 and earned 30, 30 & 10 points at their three events. Their point total will be 60 (30+30) up to 4 October,  then 70 (30+30+10) on 5 October when the next allowable event slot is opened.

General Rules

Changes were made this season to simplify the Strength of Field Multiplier (SFM) process for all teams and provide a greater clarity in advance of all events. The World Curling Championships and Grand Slam of Curling series will have a defined SFM already outlined to start the season:

Strength of Field — Set Point Events for 2022–2023 Season
World Championships11.0
GSOC — Players Championship10.0
GSOC — Masters, National, Open10.0
GSOC — Tour Challenge & Champions Cup9.0

Tour Cashpiels and Playdowns / Special events will utilize a Strength of Field Multiplier and can reach a maximum SFM as follows:

Strength of Field — Tour Cashspiels for 2022–2023 Season
Tour Cashpiels – Maximum7.0
Importance factor increase for Special Event / Playdowns
Nationals65% to a maximum of 9.0
Europeans & Pan Continental65% to a maximum of 9.0

Note that all SFM calculations are rounded down to the nearest half point (0.5). For example, if Strength of Field Multiplier is calculated at 4.25, then the event will use a 4.0 Strength of Field Multiplier event; 5.76 would use a 5.5 Strength of Field Multiplier event, etc.

Strength of Field Multiplier Calculation

Team total:

Team contributions are calculated based on the WCTRS ranking as of the Tuesday prior to the event. Each eligible team that competes is included and the contributions are as follows:

WCTRS RankingSFM Contribution
10.45
20.44
30.43
40.42
50.41
60.40
70.39
80.38
90.37
100.36
110.35
120.34
130.33
140.32
150.31
160.30
170.29
180.28
190.27
200.26
210.25
31-500.20
51-1000.15
101-2000.10
201+0.05

Teams scale:

The teams contribution total is then scaled to normalize to a 24 team event. The formula is as follows:

24 / N where N equals the total number of teams playing in the event.

Teams factor:

For Tour Cashspiel eventsthe minimum number of teams for CTRS inclusion is eight. The formula to factor this in will be determine as follows:

1 + (n – 16) * 0.03125 where N equals the total number of teams playing in the event.

Purse factor:

There will be no purse factor calculation for 2022–2023 season.

Importance factor:

National Championships will have an importance factor bump of 65%. Total amount will be multiplied by 1.65

Also note that single knockout formats will receive a 25% reduction of total SFM before adjusting for base points.

Base points multiplier:

Once SFM is determined (either through calculation or pre-season set total) teams will earn points based on their final ranking as follows:

PlacingBase Point Value
1st7.50
2nd5.50
3rd – 4th4.25
5th-8th3.00

Note: if a bronze medal game is played to determine third place then the bronze medallist will receive 4.25 * SFM and the fourth place will receive 3.00 * SFM.

Note: An eight team field will have four playoffs positions, assigned the four SFM values above. Should an event have two semi-finalists, the SFM values would be 3.625 = (4.25+3)/2

Points-Per win is calculated as 0.375 * SFM * number of team wins for teams that do not make the playoffs.

Tie-breakers within the rankings

Note that there is no ties or effective ties.

If teams are tied at any point in the rankings, ties will be broken as follows:

  1. If one team has a lower number of counting events than the team they are tied with, the team with less events will be ranked higher
    1. Example – Team A has 140 points in seven events and Team B has 140 points in eight events; Team A is ranked higher than Team B
  2. If a tie cannot be determined by point one, each team will remove their lowest counting point total and totals will be recalculated until the tie is broken:
    1. Example – Team A has 140 points in eight events with their lowest counting event being a “10”. Team B has 140 points in eight events with their lowest counting event being a “5”.
    2. Team A removes their “10” and now has 130 points in seven events. Team B removes their “5” and now has 135 points in seven events. Team B is now ranked higher than Team A

Challenges

Challenges for registered teams or point allocations must be made within seven days of the event and submitted to the following email addresses:
