The Scoring system is designed so that the team with the lowest Final Factor wins the event. The following is an explanation on how this Final Factor is arrived at and a description of the variables that make up the calculation.
For this example, each team comprises a minimum of 4 competitors and each competitor nominates a lap time in whole seconds that they believe they can maintain while on the circuit. Those nominated lap times (in seconds) are averaged and divided into 6 hours to give a theoretical maximum number of laps that could be achieved by the team. This number is then doubled and rounded to the nearest whole number to take into account “Bonus Laps” to arrive at “Goal Laps” for the team.
4 drivers Driver #1 nominates 1:15.00 = 75 seconds
Driver #2 nominates 1:20.00 = 80 seconds
Driver #3 nominates 1:19.00 = 79 seconds
Driver #4 nominates 1:12.00 = 72 seconds
Total = 306 / 4 = 76.5
21600 (6 hours) / 76.5
= 282.35 x 2 = 564 Goal Laps
Team Managers to complete Competitors Lap Time Nomination Form (included in Team Manager’s Kit) and submit it to the Event Secretary by 5.00pm on Saturday 7th March, 2009 Team Managers may change their competitors’ nominated times by submitting a Competitors Lap Time Revision Form no later than 9.00am on Sunday 8th March 2009 to the Event Secretary or their representative.
A Bonus Lap is reward for maintaining regularity and is awarded when the driver completes a lap within + 0.99 seconds of their nominated lap time.
A Penalty Lap occurs when the driver completes a lap under their nominated lap time.
A Changeover Lap occurs when a driver leaves the circuit i.e. at a changeover. The in-lap of the incoming car and the out-lap of the outgoing car (a total of 2 laps, combined time exceeding 2:30 minutes) are not counted. The software automatically recognises a period in excess of 2:30 minutes and generates a Changeover Lap. It is shown on the print out as *****.
Achieved Laps is the number of laps actually completed by the team, varied by the addition of Bonus Laps or subtraction of Penalty Laps.
* Regularity Factor
Regularity Factor is the difference between a driver’s fastest lap time and the average of their slowest 5 lap times.
Factor 1 is Goal Laps / Achieved Laps
Example: 564 / 352 = 1.602
Factor 2 is obtained by averaging all the drivers’ Regularity Factors
e.g. Driver # 1 = fastest lap (1:15.10) and average of slowest 5 laps (1:18.28), factor = 3.18
Driver # 2 = 3.12
Driver # 3 = 4.87
Driver # 4 = 4.42
These factors are added and averaged to determine the team’s Factor 2, in this case = 3.897
The winning team has the lowest Final Factor.
The Final Factor is determined by multiplying Factor 1 and Factor 2.
In the case of the example, this is 1.602 x 3.897 = 6.242
