I saw on the live stream that all the competitors had to wear impact vests. Which could have a pocket in it for a competition GPS
Also that 70% of the score was based on height of the jump.
With so many GPS devices available today I'm surprised that each competitors wasn't given a GPS to wear that would say who did get the highest etc.
They could even award a prize for the highest jump of the competition and points during the rounds.
I know that King of the Air is more than height but it is weighted very heavily so why not have accurate measurements.
How many GPS makers would want to have their GPS part of a competition like this?
