Construction of a human water ski pyramid. Could you do it?

Here's a POV look at the construction of a "double-top 4 tier" human pyramid from Wednesday night's Backwater Gambler's Water Ski Show. Olivia is wearing the GoPro and climbs up 3 levels to make it to the top.  Then, she and the rest of the team have to bring it back down and into the beach without falling.  Here's what the pyramid looks like from the audience perspective.  Olivia is on the top left of the pyramid.  She leaves the dock on Derek's shoulders (4th guy from the left).

Here's how it all gets put together and taken down from Olivia's perspective:

That's how it looks when done flawlessly. Wanna see how I do it?
Here's my point of view.
