OK, just figured out the reason for the odd spikes in the torque curve
(top graph in the preview)
The shape of the teeth is such that the contact point between them moves up and down the radius of the sprocket. In the case where the tip of the chain tooth is in contact with the lower part of the drive tooth, then you will get a mechanical advantage. The key is though, that the integral of that advantage will be zero.
I knew that Mech Eng degree would come in handy some day.

Like isn't the word really.
It's a bit sad that they've thrown so much effort at a problem that they lack the understanding to solve, while simultaneously falling into the trap of trying to prove themselves right, instead of trying to prove themselves wrong.
