TC1 test prep

This page is for people preparing for the Level 1 Chief of Timing and Calculations Test.

Update: 11/3/12 This page assumes that you have some basic knowledge of timing a ski race. If you have never timed a ski race before and do not have a command of the basics of using Split Second timing software, you should visit the New Timers page on this web-site and you should consider attending my clinic for Never-Evers on 12/15/2012. While I get these sites up and running you can also visit my YouTube channel and find much of what you are looking for there:

On this page we will go through how to:

A) Complete a Timing Technical Report (TTR)

B) Calculate an Equivalent Electronic Time (EET) (skip there)

C) Do a Penalty Calculation (skip there)

D) Other resources and helpful videos (skip there)

Please budget 3 to 6 hours to work through this material. We will be using real data from a real race. (Eastern Cup Men's GS, March 3, 2012) I would like you to appreciate that you will encounter errors. These were real mistakes that happened during the course of a real race.

A) Complete a Timing Technical Report (TTR)

The first thing that you need to do is download the actual race files that were used to time this race. (Right Click on the link to get the option to save the file to your computer!)

This is the System A file from the race (SysARaceFile.NatFIS).

This file was used for System B Run 1 (SysBRun1RaceF.NatFIS).

This file was used for System B Run 2 (SysBRun2RaceF.NatFIS).

You will need this: Blank Timing Technical Report (TTR)

The data that you will use to fill out the form can be found in these PDF's:

Raw timing tapes produced by Alge Timy's during the race.

Split Second System A Timing Log (can also be found in the race file above).

Split Second System B 1st Run Timing Log (also in corresponding race file).

Split Second System B 2nd Run Timing Log (ditto).

Start Hand Times

Finish Hand Times

Fastest times for each run can be found in the System A race file.

This file contains the official results that were signed, scanned and sent to FIS.

This file contains the current homologation numbers for timing equipment.

Now that you have all of the necessary data and forms you should watch this video where I go through filling out a TTR. It's long, 49 minutes, but the form is complicated and it takes a while to fill it out correctly.

Now let's get to the form:

(You can cheat by looking at the completed form, but try not to.)

1) In the upper right corner there is a space for the race code. You can find the proper code for this race on this FIS page.

2) On the same page you can find the Location, Nation, Discipline, Gender and Date. Note that the proper format for the date is: dd/mm/yyyy.

3) The Event Name is "Eastern Cup GS's."

4) You can cheat and look on the completed report to find the model numbers and serial numbers for the timing equipment I used. I encourage you to take a moment to locate the model numbers and serial numbers of your timing equipment.

5) This form used old homologation numbers. The 2012 homologation numbers can be found here.

6) You may also cheat and look to find out how to fill out the "scoring and results preparation" section. You should always be using the latest version of Split Second. In the software you go to "Help --> About: National/FIS Scoring Software" and it tells you the version and the date.

7) Connections to the start should be all cable. You should also have radio communication to the start. If this is not true at your mountain you either know more than this website can help you with, or you are headed for trouble.

8) Power-On Time: You should turn on your timers as soon as you arrive in the morning. For me, that's 6:30.

Now we are getting to the important part!

9) Look at the raw timing tapes and find where it tells you the synchronization time for Run 1.

10) There is no official record of the Hand Synch. This was done at 8:56.

11) You can also find the "Synch confirm at +1 minute" data on the raw timing tapes.

12) The two timing logs (System A; System B Run 1) will give you the start, finish and elapsed time for the first competitor. (Note that we used a snow-seed for this race so the first few bibs were drawn from the back of the pack.)

13) There are two small sets of parentheses ( ), ( ) in the "Finish TOD First () ()" box. These are poorly explained. In the first set of parentheses you should put the bib number of the first athlete to complete the first run. In the second set you do the same for the first athlete in the second run.

14) Find the Finish Hand Time for the first competitor here.

15) Find the Start Hand Time for the first competitor here.

16) Subtract the two times to get the Hand Time First Competitor.

17) Repeat steps 12-16 for the Last Competitor of the First Run.

18) Look in the Split Second System A Race File and find the best time from Run 1. (Remember the part about putting bib numbers in the parentheses!)

19) Repeat steps 12-18 for the Second Run.

**Issues and errors: The first competitor of the second run was bib 57. The hand-timer erroneously wrote 37. In any case, bib 57 did not finish and thus does not appear on this form. Also, the last competitor on the second run start-list was bib 21. This was entered into the form erroneously. Bib 21 did not start. The last racer to start and finish the second run was bib ?____?**

20) All times were from System A. There were no timing anomalies. The other boxes are self-explanatory. Sign it and you're done with the hardest part of prepping for the TC1 Exam!

B) Calculate an Equivalent Electronic Time (EET)

To complete this activity you need the following:

Blank EET form (or just paper if you're mathy)

Start Hand Times

Finish Hand Times

Split Second System A Race File (SysARaceFile.NatFIS).

(Right Click to download files!)

We will be doing an EET on the Second Run time for BIB 65!

Watch this example video. (It's 40 minutes long.)

1) Find the second run hand-times for Bib 65.

2) Identify the five racers before and five racers after that have starts and finishes.

3) Calculate the hand-times for all eleven of those competitors.

4) Open the race file in Split Second and find the System A times for the ten competitors around bib 65. (Remember we are pretending that 65 doesn't have an electronic time.)

5) Subtract the System A times from each of the hand times. Keep track of + and -.

6) Add up all of the values in step 5 and divide by 10. (Average difference.)

7) SUBTRACT the time in step 6 from Bib 65's hand time.

8) The result is Bib 65's equivalent electronic time (EET).

Here is my worksheet for this calculation.

Now that you can do it by hand...

Here is the Excel Spreadsheet that will do it for you.

(Found in the Master Packet of Forms).

C) Do a Penalty Calculation

For this activity I walk you through a basic FIS Penalty Calculation. It is not much harder than a USSA Penalty Calculation. If you can do the FIS version you can do the USSA version. At the end of this I link to videos where I go through calculating more tricky penalties.

To complete this activity you need the following:

Blank FIS Penalty Form (Found in Master Packet of Forms)

First Page of the FIS Points List (this changes every few weeks!)

Split Second System A Race File (SysARaceFile.NatFIS).

(Right Click to download files!)

Watch this video. (It's 21 minutes long.)

1) Open the race file in Split Second and sort the competitors by FIS points --> ascending.

2) For lowest five point holders, copy the bib, name, nation and points into "The best 5 at the start." Be careful to use their bib and not their start number. Be careful not to use any DNS athletes. (DNS = Did Not Start)

3) Sort the competitors by "Combined --> ascending" (total time, best on top).

4) Copy the top ten finishers into "The best 10 at finish" (bib, name, nation, FIS points.)

5) Find the lowest point holders in the top ten and copy their points into the column labeled "Best 5."

**The software does the Race Points for you, but the software does everything for you. The point of these help pages is to learn how to do calculations manually.**

6) Find the correct F-Factor on the first page of the points list. (Note that we are using the list that was valid for this race. For your race you need to use the list that is currently valid. It can be found here:

7) For each of the competitors that you identified in step 5...

a) Divide by the winner's time.

b) Subtract 1 from the result of 7a.

c) Multiply the result of 7b by the F-Factor. (feels like doing taxes...)

The result of 7c is the Race Points for that competitor.

8) Repeat step 7 for all of the best 5, out of the top 10 finishers.

9) Add up all of the FIS points in "The best 5 at the start" and put the result in both of the box B's.

10) Add up all of the FIS points for the best five, out of the top 10 finishers, and put the result in both of the box A's.

11) Add up all of the Race Points for the best five, out of the top 10 finisher, and put the result in both of the box C's.

12) Calculate A+B-C, put it in its box.

13) Divide the result by 10 (that's what ": 10" means) and put it in its box. ***Round to the hundreths. If your result is 14.543 write 14.54. If you result is 18.565 write 18.57.***

***Confusion Alert!!!***

14) The "Correction Value" is the Z-Value on the table. More and more this is 0.00, but not always, so you need to be careful.

***The number that you want to write in the box is the NEGATIVE of the number on the first page of points list! If the value on the FIS sheet is 1.28, you write -1.28 on the form. If the value on the FIS sheet is -0.37 you write +0.37 on the form!***

15) For the "Category Adder..."

a) first find the Race Level up top (if you're running something higher than a FIS or an NJR race then you are hopefully more advanced than this web-page.)

b) next find the appropriate adder in the bottom section and put it in its box on the form.

16) Add up the values in the three boxes from steps 13-15. This is your "Penalty Applied." (Make sure it's not less than the minimum penalty allowed...)

That's a Basic FIS Penalty.
