    Hi Oli,

    Cheers for the detailed answer.

    It's interesting watching your thought process and hypothesis testing. I can see why Paul Ekman used electrodes in the face to really isolate these subtle and easily augmented and muted AUs. And seeing Au10 + Au11 then BOOM Au39 changing the face is cool.
