Doing some bistromaths on the stated hover performance.
With a 231lb empty weight, 180lb rider, and 5 gallons of kerosene (ultra light version) you get
104kg + 81kg + 15 kg = 200kg
sfc of a Nike is 40 grams / (kN second) (Should have gone with Hawk ;) )
Lets say hover thrust on a nice still day will be around ~ 1.9kN -> 76.7grams per second of flight.
Assuming I've not made any mistakes that gives roughly 3.5 minutes of hovering flight on that 15kg of fuel (ignoring the fact the vehicle gets slightly lighter as the fuel burns off).
That sort of matches up with the spec, assuming the 10-22 minutes stated is for a lighter human on the experimentally licensed version of the vehicle.
