In reply to Paz:
I could have sworn I saw a clip on youtube of some basketball payer jumping five foot from a standing start.
Actually of course a vertical leap is measured from the difference between fingertip stretch on the floor and in the air, isn't it? So jumping five foot with legs tucked up is no indication.
I believe this dyno is 102' from jug to jug and was only achieved on the 76th day of trying, so it's probably quite hard.
It would undoubtedly be a mighty pisser if a static alternative were discovered, assuming that is that the problem wasn't simply an eliminate in the first place.
