A single powermeter with two frames is still a big number subtraction problem.
But the bigger point is that
any deflection will show a power loss, and it is still
best for power transfer to have a stiff frame. If there is no local minimum you are trying to hit, there is no reason to quantify any property other than stiffness. In other words, if stiff is better than less stiff, than the objective is to make the frame stiff. I don't think you need a powermeter to make this argument. At best, you can say that "less stiff" is
no different than stiff, and most don't really believe this.
