Sweepers shall then communicate their evaluation to the skip and sweep as needed. Timing is one of the techniques used to evaluate the weight of a moving stone. Timing:
Measure the time elapsed before the stone travels a fixed distance between two pointsUse benchmarks in the house close to the area where the player starts delivery (ex. back line and tee line, back line and hog line)For the same distance, the shorter is the recorded time, the heavier is the weight and the greater is the distance travelled. Timing Methods:
With a stop-watchBy counting in your headAny other personal method used by a player A Few Reasons Why Players Should Time:
 For the sweepers: quickly judge the weight of the stone, communicate the information to the skip and sweep as needed For the delivering player: better evaluate the required weight  For the sweepers and the skip: better judge the weight of the stone throughout the game  For all players: compare the speed of your club’s ice to that of other clubs   Features to Consider:
 It is useful to exercise judgment regarding the weight of the stone before using a stop-watch  At the beginning of a game, the ice may be frosty because the pebbles are fresh, therefore the ice is slower  The pebbles are progressively polished due to sweeping and the ice becomes faster If no stone has been delivered in a certain area, the surface will be slower even though you are playing a second end  The center of the ice always becomes fast because it is used more frequently for delivery and sweeping, but at the end of a game, this area should also be monitored because the stone may come to rest more quickly since the pebbles are worn Sweepers are responsible for judging the weight of the stone  Example: Timing between the back line and the hog line: 
 The delivering player initiates his or her delivery When the stone in the player’s hand touches the back line, sweepers activate their stop-watches When the stone touches the hog line (at the delivery end), sweepers stop their stop-watches  Depending on the time elapsed, sweepers can determine the weight of the stone . 
| Elapsed Time Example: From the back line to the hog line. |  
|  |  
| 3,3 sec. = Back line |  
| 3,5 sec. = Draw |  
| 3,7 sec. = Guard |  
| 3,9 sec. = Sweep! |  |
