Re: How did teams think of using the 'reverse curl' to get on the bar?
A strategic analysis showed that hanging from the side bar was more versatile from hanging from the top bar. You can hang from the side bar from the floor in the near zone, while the top bar needed to be hung from the middle zone or the bump.
Once you determine the strategic advantage, you then start thinking of ways to elevate, when the single joint "curl up" seems the simplest as it takes few motors.
My team could not figure out a mechanism to hold ourselves up on the side bar, so we were going to go for the simpler top bar. We were ultimately inspired by 1625's post ship video to make a hanging arm that grabs the bar from both sides and elevates using a single joint. You'll see it at many North Atlantic off seasons.
