What information is needed to calculate a Split?

Each Split point relies on three bits of information, Name, Timing Point, and a minimum valid time. The minimum valid time is calculated using either a minimum time or by using distance with a speed/pace. Together these bits of information help the software determine if a chip read is valid for each specified split on the course. You can also reference General Splits Setup for more information on Splits.

• The Name of a Split should be something that describes a location on the course without making the name too long or complicated.
• The Timing Point tells the software which raw data to use for the split.
• The Type of Sport is only necessary for defining the start of a race. When using This is the Start, the last chip read will be taken and defines the Split to be used to calculate Chip Time. When using one of the available sport types, the first read will be taken. Sport type will also provide a recommended speed or pace to use for easy setup.
• Distance is defined from a previous point on the course. For the start of a race, this will be a distance of 0. Further Splits can be defined either from the start or from any previous split.
• Pace/Speed/Time is where you define the minimum or maximum time a participant can complete the specified split.

This file again has 3 Splits setup, one for each of the 3 Timing Point locations on the course. 

Start Split

This first row defines the start of the race where we want to collect the last chip read for each participant as they leave the start line. This is also known as the Chip Start if you are scoring based on Chip Time. The reason we want the last chip read here is that participants who are standing on the start line will receive several chip reads before the race starts. Most of these will be ignored because they are before T0 but some participants will still get multiple reads after T0 because they are moving slowly at the start of the race. The last read is the most accurate read as a participant leaves the start line.

• We set the name to Start since this is the start of the race. This is shown on the course map as the first decoder labeled Start.
• We set the Timing Point to STARTLINE.
• Since this is the start, we set the type to This Is the Start (last read).
• Since this is the start of the race, there is no distance up to here. This option is greyed out.
• We are using Race Time which is the time from the Start Time (T0). We set a min time of negative 5 seconds and a maximum time of 2 minutes. This defines a start range of 2 minutes from T0. Any participant starting after 2 minutes will not get a start time. If it is going to take more than 2 minutes for everyone to cross the start line, this value should be increased.

Here we can see a breakdown of the above Start split. This shows us the time range in which a chip read is valid for this split point. For a detailed explanation of how this information reflects a participant's results, please see Participant Splits & Troubleshooting.

	Time of Day	Race Time
Min	07:59:55	-00:00:05
Max	08:02:00	00:02:00

 

5k Split

The next row defines our 5k split point where we want to collect the first read as each participant passes this location on course.

• Split name is 5k.
• We set the Timing Point to SPLITPOINT.
• The type of sport should be set to the type of sport you are timing, this event is a running event. 
• We set the distance to 5000 meters and then define this as the distance (From Start). We can see this represented on the course map by the blue line.
• By default when selecting running as the Type of Sport this is set to use pace (min/km or min/mile according to your event file's units or measurement), here we are using min/km with a minimum (fastest) pace of 2:30/km and maximum (slowest) pace of 20:00/km. When using a speed/pace with distance, the valid time window will be calculated relative to the previous split.

Here we can see a breakdown of the above 5k split. This shows us the time range in which a chip read is valid for this split point.

	Pace	Race Time From Previous Split
Min	2:30 min/km	00:12:30
Max	20:00 min/km	01:40:00

Finish Split

The last row defines our finish split where we want to take the first read as each participant crosses the finish line decoder.

• Split name is Finish.
• The Timing Point is set to FINISHLINE.
• We set the type of sport to Running.
• Distance is set to 10000 meters and defined as (From Start). We can see this represented on the course map by the green line.
• We are again using the default pace settings according to the type of sport. 

Here we can see a breakdown of the above Finish split. This shows us the time range in which a chip read is valid for this split point.

	Pace	Race Time Relative To Previous Split
Min	2:30 min/km	00:12:30
Max	20:00 min/km	01:40:00

Final Splits Setup

Now that we have looked at each individual split this is what the entire Splits setup will look like.
