My question is very basic, really. Stan says that it 
differentiates at the BR, 885140 seems to say that the torque 
split is variable when differentiating. You say they're both 
right. How's that? I don't care about the inputs, the Torsen 
doesn't care or "know" where they came from (slip vs traction), 
I'm just concerned with the device's outputs.

How about this thought experiment.  Put a torsen quattro (with matched tires
and zero toe and camber on all wheels) on a pair of chassis dynomometers.
There should be no slip angles involved.  The dynos are operated at the same
speed, and initially at the same load matched to the drivetrain output
power.  Now reduce the load on one dyno slightly.  Does the torsen apportion
torque to the dynos at less differential than the bias ratio?  Or does it
attempt to speed up one end by forcing torque to that end at the bias ratio?
