Transcript of BASIC TIMING & CALCULATIONS. BASICALLY, THE CHIEF OF TC Is responsible for supervising, documenting...
BASICALLY, THE CHIEF OF TC• Is responsible for supervising, documenting and enforcing the quality
control of actual timing and results
• The Chief of Timing and Calculations should not also be the individual operating the electronic timing equipment or the timing/race result software.
(Exception: USSA non-scored events, i.e. YSL, due to staffing concerns)
Chief of Timing and Calculations• Coordinates officials at the start and finish
• Verifies synchronization of the timing
– Manual/hand timekeeping
– Electronic timekeeping
– Is responsible for the accuracy of the timing
– Responsible for the accuracy of the official times
– Completes and signs the Timing & Data Technical Report (TDTR) for all scored events and non-scored championship events, including Masters Championships
– Delivers Timing & Data Technical Report form for TD’s review and signature
• Following officials are under the direction of the Chief of Timing and Calculations:
– Starter
– Assistant Starter
– Start Recorder
– Chief Timekeeper
– Assistant Timekeepers (Manual/Hand Timekeepers)
What is Time of Day Timing?Time of Day (ToD) Timing - Time of day timing is the time a racer
leaves the start and arrives at the finish taken on continuously running, synchronized timekeeping equipment.
When did he leave = Start Time
When did he arrive = Finish Time
How long was his trip = Run Time
TIMING REQUIREMENTS:TIMING REQUIREMENTS:• Review timing rules; level of race dictates timing system requirements – 1 or 2
homologated timing devices
• Time of Day (ToD) timing is required
• Computer software that calculates net times must use precision of ToD as used in the timing device
• Timing equipment must measure times to 1/10000 (.0001) precision
• Timing equipment must display times to at least 1/1000 (.001) precision
• Manual timekeeping is required for all levels of USSA-sanctioned competition
• Forerunners are timed…BUT their times are not announced and are not published!
Subtracting Electronic Times:Subtraction begins at the last position and times are truncatedCross a colon – borrow 60; cross a decimal – borrow 10REMEMBER: 1 Minute = 60 Seconds

1:02.01A RACER’S ELECTRONIC TIME IS NEVER ROUNDED OR AVERAGED!
What is Manual/Hand Timekeeping?• Manual/hand times are taken with synchronized, manually-operated timing
devices (stopwatches) that are independent of the electronic timekeeping.
• Start and Finish Manual/Hand Timekeepers are placed in an area where they will not be disturbed.
• Device should be held steady using bony ridge of first joint on index finger to activate/depress the button on button-type watches
• Timekeepers record the times they see/hear
• Timekeepers take and record a time for all competitors who cross the finish line regardless of the competitor’s status
• Timekeepers DO NOT make decision on DSQ status
START / FINISH FOR MANUAL TIMEKEEPERS• Start time is taken when the racer’s lower leg crosses the start
line
• Finish is taken when any part of the competitor crosses the finish line
• Manual Timekeepers must be consistent
Start/Finish Timekeeper Recording Form
• The same form is used by both Start and Finish Manual/Hand Timekeepers/ Recorders
• Be sure to fill in all information at the top of the form
• Form provides a record of an event/starts as they actually occurred
DO NOT PRE-NUMBER FORM!
Replacement Time (Equivalent Electronic Time – EET) When electronic timing systems fail, calculation of a replacement time is required.
• The calculation is based on:
– Calculation of a replacement time based on System B time in lieu of the missing System A electronic time, or
– Calculation of a replacement time based on manual/hand time in lieu of the missing System A and System B electronic times
• The calculation is performed by:
– Comparing the 10 times closest to the missed electronic time (usually 5 before and 5 after the missed time)
– Dividing the sum of the differences by 10 and either truncating or rounding which supplies the correction value
– Applying correction value to System B or calculated manual/hand time
• A replacement time (EET), when required, is an official time and is valid at all levels and types of competition.
Replacement Times(Equivalent Electronic Times - EET)
• When the electronic time is missed on the primary system (System A), it will be necessary to calculate a replacement time from the secondary system (System B)
• If both the primary and secondary systems fail, you must calculate a replacement time from the manual/hand timekeeping
• A replacement time is a valid time!
OTHER TIMING SCENARIOS
• If System A times are unavailable for a major portion of the field, System B times must be used for the entire field
• If both System A and System B times are unavailable for a major portion of the field, calculated hand times must be used for the entire field
Replacement/Equivalent Electronic Time WorksheetThis is the basic/manual system of calculating a Replacement (EET) System A Time usingSystem B Times or a Replacement Time (EET) when calculation of manual/hand times is required

COMPUTER-GENERATED REPLACEMENT TIMESCOMPUTER-GENERATED REPLACEMENT TIMES
Just 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!
Do not wait until the end of a run/race to calculate a replacement time; they must be calculated as soon as possible
ALTERNATIVE CALCULATION ALTERNATIVE CALCULATION SYSTEMS:SYSTEMS:• Excel spreadsheets• USSA 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!
Race Day Scenario – The FinishRace Day Scenario – The Finish• A racer commits a gate fault • His racing speed carries him over Finish Line• The racer hikes back over the line and completes passage of the missed
gate

Miscellaneous TopicsMiscellaneous TopicsVertical Drop, Minimum Time and Minimum Penalty in Scoring a USSA Alpine Race.
1. Races that meet all technical standards:
If all requirements of a competition are met, i.e. vertical drop and minimum time, but the penalty calculates below 15.00, the minimum penalty of 15.00 will be applied.
The minimum penalty is valid for all events/genders.
2. Races that do not meet vertical drop requirements:
• If the minimum vertical drop requirement is not met, but the minimum time requirement is met,
- greater of the calculated penalty
OR
- the minimum penalty of 30.00 shall be applied.
3. Races that meet neither vertical drop requirements nor minimum time standards
• If the minimum vertical drop requirement and the minimum time requirement are not met, then
- the greater of the calculated penalty
PLUS- the additional penalty
OR - the minimum penalty of 30.00 shall be applied.
NOTE: If the minimum vertical drop requirement is met, the minimum time requirement does not apply.
4. MINIMUM VERTICAL DROP PER RUN, ALTERNATE MINIMUM TIME STANDARDS AND ADDITIONAL PENALTY:
EVT MIN VD ALT MIN TIME ADD. PENALTYDH* 400 m 60 sec. combined/max 2 runs 26.00SL 100 m 50 sec. combined for 2 runs 12.00GS 250 m 50 sec. combined for 2 runs 17.00SG 300 m 40 sec. for 1 run 21.00
NOTE: DH “combined/max 2 runs” does not eliminate60-second minimum time for 1-run DH.
Falls in Finish/Timing Area:
• ACR states that a binding release more than 2 gates above the Finish line in SL, GS or SG or
• More than 1 gate above the Finish line in DH shall be considered as a clear DSQ
[U628.1.5, U629.4]
A racer who crosses the finish line after committing a gate fault is DSQ, NOT DNF
Regular Interval –
DH, GS and SG competitors leave the start gate at setintervals pre-determined by the Jury
DHT starts must also be at regular intervals
Intervals apply to all race levels
Start Commands: Regular Intervals• Regular Interval Start Command (DH, SG, GS)
– Starter begins sequence with a warning “10 seconds”
– After a 5 second pause, starter counts down to “5, 4 3, 2, 1, Go”
– Racer may start 5 sec before until 5 sec after “Go”
– Failure to start within that 10 second window is an early or late start and will result in DSQ
Start Referee will record the failure to start properly and report to Jury
MINIMUM INTERVALS
• Minimum intervals between consecutive competitor starts in a regular interval event are:– DH – not less than 40 seconds, includes DHT– SG – not less than 40 seconds – GS – not less than 30 seconds
Irregular Interval –
SL competitors leave the start gate at irregular intervals.
Chief of Timing & Calculations or his assistant tells the Starter when each competitor should start in agreement with the Jury.
Start Command: Irregular IntervalsIrregular Interval Starts (SL)
– Starter announces “Ready”– Followed, a few seconds later, by “Go”– As in regular interval event, racer has 10 seconds to
start– Failure to start within about 10 seconds results in DSQ

Second Run Start Order• For scored events, racers are ranked according to First Run Time• The order for a pre-determined number of racers is then reversed (flipped):
30 or 15 – this is a “bibbo” • 30 is standard; Jury may limit to 15 – must be announced 1 hour prior to
start of first run• Special rules for Second Run Start Order apply for
– USSA non-scored events, i.e. Age Class, YSL– Bibbo with a tie at the pre-determined flip position– Collegiate events– “Golden Rule”
Bibbo - procedure used to determine second run start order for 30 or 15 fastest first- run competitors at USSA-scored events.
NOTE: A standard bibbo is 30; the Jury may choose to reverse 15 but they must announce this 1 hour prior to the start of the first run.

BREAKING THE TIES & CREATING THE LIST:
1. Rank all competitors by first run time
2. Break all ties by giving higher/better position to competitor with the higher start number
3. Look for ties at flip position (15 or 30)
4. Include the ties and flip the competitors; e.g. if there is a 2-way tie at the flip position, you will flip 16 or 31; if there is a three-way tie at the flip position, you will flip 17 or 32, etc.
1. Seed Points - a numerical indicator of a competitor's individual ranking with all other competitors. Seed Points are used only at scored events.
NOTE: USSA Seed Points may only be corrected by USSA,
FIS Seed Points may only be corrected by FIS.
Foreign competitors with current FIS inscriptions and without USSA Points entering USSA non-
FIS events are be seeded with their FIS Points. If part of the penalty, FIS Points are used.
They must, however, have a USSA “X” membership.
If these competitors have current USSA Points, their USSA Points must be used for seeding
and required penalty calculation even if their USSA Points are higher than their FIS Points..
2. Race Points - a numerical indicator showing the relationship between a competitor and the winner of that specific race; race points are calculated only at scored events.
3. Penalty - numerical indicator that equalizes races of same event with different methods of calculation for FIS and USSA; a penalty is calculated only at scored events.
What is a “Race Result”?
A racer’s score for a given event isRACE POINTS
+
PENALTY POINTS=
RACE RESULT
When a Race Result is equal to current Seed Points, a competitor is skiing their points
When a Race Result is lower than current Seed Points, a competitor is showing improvement
Seed and Draw Board - display boards where cards containing competitors’ names, club or team affiliation and seed points, if applicable, are posted.
Double Draw - simultaneous drawing of the competitor number (the place they hold on the seed board) and the bib number by the Referee(s); a double draw is used only for scored events.
ELECTRONIC BOARDS• Electronic draw/seed boards must have the capability to
simultaneously and legibly display the entire competition field. Simultaneous display of all competitors allows all Team Captains and officials to verify the overall accuracy as well as additions and deletions to the starting order in “real time”.
• Using the race result software to display portions of the competition field is not acceptable.
COMPUTER-ASSISTED DRAW
The Jury may allow a computer-assisted Draw:
1. USSA events – with the approval of the Team Captains
2. FIS events – with the approval of the Team Captains as noted by their signature
Snow Seed - referred to in the rules as a “Start Order in Extraordinary
Conditions”, is a process whereby 6 competitors are drawn from the last
20% of the field.
- These 6 competitors are shown with an asterisk (*),
- These 6 competitors start prior to start #1 in the reverse order of their
assigned start positions.
- Snow Seed is only valid for DH, GS and SG. A snow seed may be drawn at both scored and non-scored events. [621.9]
