So taking the averages, the V1 beat the 9500i on every Ka band but not by much:
35.5 = 87% of the distance
34.7 = 95% of the distance
33.8 = 99% of the distance
With 127 feet being the most distance. If you were travelling 55 mph, you would pass 127 feet in just over 1 second.
So basically the 9500i and V1 alerted at the same time, and about 1 second later on 35.5.
Also interesting that the 9500i was king of the "Forward Facing" test, beating the V1 - which only got 83% of the distance of the 9500i.
