CALCULATING A REPLACEMENT TIME AKA EQUIVALENT ELECTRONIC TIME (EET)

1. CALCULATING A REPLACEMENT TIMEAKAEQUIVALENT ELECTRONIC TIME (EET)

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. Copies of Replacement Time (EET) calculations must be submitted with TDTR’s forwarded to assigned USSA TWG representatives.

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!) • Divide the sum of the 10 time differences by 10 and round, if required, to give the correction. • 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 FORMThe following presentation is an aid to help you understand the basics of the calculation.

5. REQUIRED DOCUMENTS: • Electronic Time Recording Form • Finish Timekeeper Recording Form • Start Timekeeper Recording Form

6. ELECTRONIC TIME RECORDING FORM

7. FINISH TIMEKEEPER RECORDING FORM

8. START TIMEKEEPER RECORDING FORM

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

13. THE VALUE OF A REPLACEMENT TIME • A Replacement Time that is calculated in accordance with the rule is a valid time! • Accuracy of a hand-calculated replacement time must be verified. USSA/FIS 611.3.2 and 611.3.2.1

14. ALTERNATIVE CALCULATION SYSTEMS: • Excel spreadsheets • Nat/FIS Scoring Software (Split Second) • HINTS: • Do NOT use Forerunners’ times • Do NOT use DNF start times • When times are in close proximity, both systems allow for calculation of multiple replacement times • Both systems may require a dedicated computer • Electronic timekeeping equipment operator should not be responsible for these calculations • Regardless of the system you prefer, do not wait until race day to learn how to use it!

15. CALCULATION: USING A SPREADSHEET

16. CALCULATION: USING Nat/FIS SCORING SOFTWARE

17. CALCULATION: USING St/Fn ToD FILL IN HEADER! • Key in: • Bib #’s • Start ToD • Finish ToD Electronic Times: Automatically entered by software. (If not working in actual race rile, input Electronic Times manually.) Print for review Select “OK” to auto assign EET in race file Complete EET & automatically assign replacement time

18. CALCULATION: USING Elapsed Timee.g. Calculating “A” (Electronie Time) using “B” or “calculated Hand Time” (Elapsed) FILL IN HEADER! • Key in: • Bib # • Elapsed Times EET not complete until Step 3 completed Print for review Select “OK”; time auto assigned in race file 3. Select

19. CALCULATION: USING Elapsed Timee.g. Calculating “A” (Electronie Time) using “B” or “calculated” Hand Time (Elapsed) Regardless of process used: “ToD” or “Elapsed” verify the following: “EET APPLIED”

20. COMPUTER-GENERATED REPLACEMENT TIMESJust because a replacement time is calculated by a computer doesn’t mean it is correct.Accuracy of a computer-calculated replacement time must be verified!
