Are they saying that's evidence of a 66" vertical? Last I checked that is nothing like the test they use for measuring your vertical.
Vertical is how high you can jump, he jumped high, but he raised his feet to clear the bar, more of a 66" hurdle. Calling this a 66" vertical is like saying Javier Sotomayor has a 96" vertical (the world high jump recod). Very impressive jump, but false advertising.
