Help with inverted phase Newbie Question

I followed the link and, interestingly, the "Wood Effect" didn't come up. So I searched the A'gon archives, and it seems it hasn't come up at all... I don't know why I remembered the WE, but I think some piece of gear I had explained (probably a theta box, they all seem to have phase inversion toggles on them) that "some" people are sensitive to the WE. Here's a link to a Positive Feedback article on it:

Be interested to hear what people think of it...

If you invert twice, you are in phase. Inverted phase is 180 degrees out of phase. Invert again, you are 360 degrees out of phase, which is really 0 degrees out of phase, which means you aren't out of phase. If that makes sense.
