I thought that was a typo, or that you were hallucinating until I watched it on YouTube. However, I think the technique that was employed, and the way the jump was measured made all the difference. When verticals are measured at, say, the football combine, the score is the difference between the height one reaches while standing flat-footed with ones arms stretched straight overhead and height one achieves overhead after jumping. In the case of the Canadian recordholder, the score was based on the height of a "box" onto which he jumped. Ungar achieved his amazing year by beginning in a deep squat, propelling himself upwards and forward, and landing on the box in a tucked position. Truly impressive, but completely useless if you are trying to catch a pass, snare a rebound, block a shot, or dunk a basketball. Apples and oranges.
