Official records aren't kept of BASE jumps, but Aiello estimates that 10,000 people around the world have jumped at some point. The number of weekly BASE jumpers is probably about 1,000 and another 1,500 people may jump a couple times a year.Aiello stopped counting his BASE jumps after his 1,000th in 2003.ost regular BASE jumpers have probably flown in a wingsuit at some point, but only a small number regularly jump in one, Aiello said. Of that number, only 20 to 50 people in the world practice the type of terrain flights Potter did, flying through canyons and just inches from rock walls and treetops.
So if you have five people, and four have 20-inch vertical leap and one has a 40-inch vertical, the median is 20 (half jump as high or higher, half jump as high or lower) and the mean is 24, thrown off by the one jumper in the group.verage is not a word with a precise meaning. It can refer to the mean or the median. The median is the point at which half the people jump the same or higher and half jump the same or lower. You get the mean by adding up all the vertical leap heights and dividing by the number of jumpers.
