1. CALCULATING A REPLACEMENT TIME AKA EQUIVALENT ELECTRONIC TIME (EET) 8/08 update AB Church

2. What is a “Replacement Time”? In the case of the failure of the main electronic timing system (System A), the results of the electronic back-up system (System B) will be valid as per the requirements for calculating a correction. In the case of the failure of both the main and back-up systems Hand (manual) times may be used in the official results after a correction has been calculated.

3. CALCULATION OF THE CORRECTION 1.Calculate the difference between the times taken by hand* and the electronic times of the 5 competitors starting before the missing time and the 5 starting after or, if necessary, the 10 nearest competitors. (A Forerunner is not a competitor!) 2.Divide the sum of the 10 time differences by 10 to give the correction. 3.Apply the correction to the calculated hand time of the competitor without an electronic time. *Hand (manual) timekeeping is required at all levels of competition.

4. CALCULATION FORM The following is provided as an aid for calculation.

5. DATA YOU NEED: 1)Electronic Time Recording Sheet 2)Finish Timekeeper Recording Form 3)Start Timekeeper Recording Form

9. Subtracting Electronic Times TIMES ARE NEVER ROUNDED OR AVERAGED! HINT: 1 Minute = 60 Seconds Cross a colon – borrow 60; cross a decimal – borrow 10 #10 57:24.83 Fn. HT -56:04.80 St. HT = 1:20.03 Calculated Hand Time 4.17 #11 57:55.79 Fn. HT -57:02.84 St. HT = 52.95 Calculated Hand Time

10. CALCULATED HAND TIMES FOR MISSING TIMES Insert the Finish Hand Time and Start Hand Time from the Recording Forms
