Timing and Results
Gone are the days of manual key entry of sail numbers and timing equipment. Today, each competitor carries a Locosys GT31 GPS data logger unit. The introduction of GPS units has revolutionised the timing and accuracy of the event. So long as the unit is switched on, carried by the competitor and returned before the closing time at the end of the day, the competitor's positions and speed can be reliably determined.
Each unit accurately records the competitor's position every second of the day. The units are normally housed in waterproof bags and strapped to the competitor's arm. Each unit is individually identifiable and allocated to a single competitor.
Results are generated daily in "near-time" when all of the competitor's GT31 units have been collected after the day's competition. The data is downloaded from each competitor's unit.
The data is processed firstly by Manfred Fuchs’ GPSResults software in order to define the course positions and course open/close times and to select all of the competitor's qualifying GPS runs. The software then calculates the speed, duration and direction of each 500m run recorded by each GT31 unit and outputs the raw results for further results processing.
These “preliminary results” files for a specific day are then read by Tim Daish’s Excel macro, SSerpant, where some more clever calculations are performed to combine the results with the appropriate competitor information from the registration file. The resulting data is then sorted and output as the various results reports we require. Result processing can also look up the wind speed and direction as recorded during the time of the run and calculate the average values; results can include speed-to-wind speed ratios and course angle sailed relative to the wind.
The day's results and an overall leaderboard are then made available on the website. Results can also be printed and posted up in the marquee.
