Race timing software for NASTAR is from Split Second Timing.
Live-timing is a feed system that receives data from Split Second software to provide close to real-time information on the WWW. https://www.live-timing.com/ . We love this app as we can check on the mountain.
https://www.splitsecond.com/ This link will take you to a page where you can download the Software, both FIS/National version and the Ski Club version. To use the software in an official manner requires payment for a USB Key fob.
You can download it to use as training to get used to the timing features.

NO racer or club wants to lose participants’ race times.
BACKUP – Ways to keep data
End of race day a racer should take a screenshot of the Live timing screen for that resort.
The Timing crew should email the race XML file to their own email address as an extra copy. A thumb drive can be used to store the XML data file for the day. See the Split Second101 training in the Documentation section.
