I recall seeing the high dive show in Great Adventure (Six Flags, in NJ) as a kid.  The divers did several performances each day, and the really high dives were 80, 90, and 100 feet.  On the other hand, they had spray pumps that made the water wavy and reduced the surface tension, so that may be why they had no restrictions like Lysanne describes.,(reply>), Spray/bubbles are not to reduce surface tension, which doesn't matter for humans. Bubbles reduce the density of the water under the surface, and spray increases visibility.,(reply>), Her medical restriction is 6 jumps per day, so as a star jumper that could be 6 shows per day.
