I think it depends on the viscous system. You are probably imagining an
always lossy system like a torque converter in an auto trans. However, I
saw a diagram and explanation of a viscous system and the claim was that
in 1/5th of a second of slippage, the "goo" between the plates would
heat up enough to lock up solid. This would apply to the center coupler.
The rear diff was still open. I don't remember what car this was on.
