Trying to see this I found that when a wave crosses a step function, https://quantummechanics.ucsd.edu/ph130a/130_notes/node149.html When the incoming wave exp(ikx) reaches an upwards step function there is a reflected wave R exp(-ikx) and a transmitted wave T exp(ik'x) what this article shows is; 1 + R = T That is, the amplitudes of the incoming wave and the reflected wave add to the amplitude of the transmitted wave If I take this into a square well then I would understand that the waves inside the well have the total amplitude equal to the incoming and transmitted wave. That is, when the wave enters the Muffin Tin the amplitude of wave is not AUGMENTED. So why is this method called "Augmented Plane Wave"?
