I don't want to debate the benefits of stiffness, or the idea of measuring only the bb stiffness and making conclusions from that data, but isn't the method here flawed?
I would think the rider can generate force beyond only their body weight?
The conditions shown make it look like the flex is only a couple of mm, "so what's all the fuss about" could be someone's conculsion.
That doesn't look too "real world" to me:
