 So the WCT moved to "Thinking time" to even out this discrepancy.With this new system, each team is given 40 minutes of “Thinking Time” plus an additional 5 minutes if the game goes to an extra end.The system is now a standard in Curling Canada championship events, though with a 38-minute limit for standard 10-end curling (four minutes for extra ends) and 22 minutes for mixed doubles.
