If your event uses more than 12 laps, this method will help alleviate the complications that can arise in CT Live due to streaming every read to every point. For events with 12 or fewer laps, you can use the Minimum Interval Duration feature without using Virtual Points. Click HERE for details.
This guide will walk you through the process of using the Virtual Points feature in a SimpleClient session to score a lapped race using only one timing line.
Configure ChronoTrack Live (If Applicable)
If you are using ChronoTrack Live to score your race, follow the instructions below. If not, skip to the next section.
- Create the event as normal.
- On the Scoring > Course tab, create any and all Timing Points and Intervals associated with your race laps.
- Create unique timing devices to correspond to each of your timing points.
It is very important that each timing device has a different name, even though the same line and controller are being used to collect the data.
- Your finished setup may look something like this:
It is not necessary to use MID when you create the devices. The RMG file will automatically apply the correct read occurrence to the correct timing device.
Creating an RMG File
- Open the Notepad program. In most versions of Windows, you can simply open the Start menu and start typing ‘Notepad’ and it will come up in a search.
- Type 6 zeros, followed by a semicolon. This acts as a filler for the MAC address usually entered in this portion of a regular Virtual Point file.
- Type 1;1; This indicates the read occurrence to be attributed to the specified timing device.
- Next, in all caps, name the timing device that the read occurrence will be attributed to.
It is very important that the names applied to each line of the RMG file correspond in sequence to a different timing device name in CT Live, even though the same line and controller are being used to collect the lap data.
- A finished line should look something like this:
- Create as many lines as there are timing laps/points/devices in your race. For the CT Live race example above, the file would look like this:
- When finished, click File > Save As…
- Under Save as type: select All Files from the dropdown.
- Name your file, then type .rmg after the name.
- Click Save and exit Notepad.
- Open a controller file in SimpleClient and select the correct session.
- Enter the Event name that corresponds to your CT Live event in the Rename Event field (EVENTXXXXX where the Xs are your Event ID number). After that, enter the first Point name in your RMG file in the Rename Point field.
E.g. If the first line in your RMG file is 000000;1;1;LAP1, enter LAP1 in the Rename Point field.
- Under Adjustments, check the Virtual Points This will bring up the Virtual Points window.
- Click Load Ruleset.
- Locate the .rmg file you created, and click Open.
- You will see the lines of the .rmg file displayed in the Virtual Points window.
- Click OK to close the window.
- Click the Minimum Lap Increment Time check box found directly under the Virtual Points field. This feature instructs the software on how long to wait before applying a valid read occurrence to a lap. This in turn prevents an athlete who has multiple reads at the line within several seconds from having each of those times applied as lap reads.
- Specify the amount of time the software should wait in seconds.
Example: The race shown above is a 5km race, and there are laps every 1km. The world record for a 1km run is 2m 12s. So, it would be best to set the Minimum Lap Increment Time to about 5% less than that time; in this case, about 126 seconds. This allows room for the possibility of someone breaking a record.
- You are now ready to stream the data. Click Select to finalize your settings and play the data as normal.
