10. ANSWER TO COURSE MEASUREMENT EXAMPLE

 
Pre measurement calibration
   
Post measurement calibration
  Start End Increment     Start End Increment
Ride 1 04000 09610 5610   Ride 1 51000 56612.5 5612.5
Ride 2 09610 15218 5608   Ride 2 56612.5 62221.5 5609
Ride 3 15218 20827 5609   Ride 3 62221.5 67833 5611.5
Ride 4 20827 26434 5607   Ride 4 67833 73441 5608
    Average 5608.5       Average 5610.25

Pre measurement calibration constant = 5608.5*1.001/0.49955 = 11238 counts/km

Post measurement calibration constant = 5610.25*1.001/0.49955 = 11242 counts/km

Use the largest constant in order to ensure the course is not short, Constant of the day = 11242 counts/km

Lap start = 34871

Lap end = 52998

Count increment = 52998 - 34871 + 100000 = 118127. Lap distance= 118127/11242 = 10.5077 km

2 laps = 21.0153 km. Required distance for half marathon =21.0975km, so Start will be 21.0975-21.0153 = 82.2 m from the finish, The course will be 2 complete laps plus 82.2 m.
