  So my answers are
time to
check my understanding of the way a torsen works.
 For simplicity lets discuss a torsen in a rear diff in a front engined,
rear drive car (as in camaro) (I don't have one!)(don't have a mustang
anymore either)
  I don't recall the torque limits but's lets assume this torsen operates up
to a 75/25 split.

#1    If driving this theoretical car around our virtual corner (sorry hard
to resist) without nearing the torque limit or traction limit (driving 3/10)
is the torque split 50/50???

No, torque is applied to the inside tire as it is turning slower.

#2  If pushed harder to the point the inside tire slips (or would in an open
diff) would I be correct in my understanding that it will spin at the same
rate as the outside tire (acting as if locked)???

YES

#3 (an easy one I assume) past that point both tires will spin at the same
rate as long as the torque split does not exceed 75/25  and if exceeded  the
torsen is uncapable of working and will operate as an open diff.  correct???

YES
