Esp. check out all the links near the bottom of the page under "FEA Model Quantifying Strain Energy" right before the Conclusion heading.

This basically shows what the GCN video shows. It only works when the test is done with the arms horizontal. We've all agreed that the force that is holding the spring energy in the flexed frame is released at around 7 oclock.
