USHPA proposes:

4.1.3 Live Tracking

Live tracking is mandatory in Category 1 events and test events. Organizers may
request an exemption at the time of bidding. Using the live tracking information
as a strategic aid to pilots is an unsporting behavior.

4.1.3.1 Mandatory Delay: In Hang Gliding, any publicly available feed provided
by the organization must have a delay of no more than 10 minutes.
