I honestly have only thought briefly about if having some center diff lock during braking would help or not. As i don't have many track hours to use to aid me to come up with a good guess.
I'm sure what the cars computer does on Auto is geared for keeping the car in control.
Seems like some people think the torque changes and others don't. It is a very complicated system and no one document seems to answers the majority of the questions about it.
I have driven a lot in loose surface conditions with a variety of Center diff settings and I've felt how different locking rates affect the cars traction and handling aspects, though at lower speeds. And while that experience doesn't qualify my opinion as any better as anyone else's , It really leads me to believe one way until I've come across some literature that conclusively shows otherwise. (Perhaps with lots of pictures for my benefit.)
