You're not finding the answer you want because it's not an easy question. Less deceleration lock means it's closer to an open diff when you are braking. Not sure of the reasons for autocross to need that because I don't have much experience with autocross. Less lock would seems to mean in that you would have a harder time to clock up the rear coming into a turn and less easy to slip/rotate which probably isn't too useful on small tight tracks.

I read a few books and have a decent amount of seat time and am only grasping the basics of what all this body and suspension tuning means on the track.

"Autocross racing places very high demands on the differential because the corners are much tighter in radius than road courses. This places an enormous burden on the chassis and differential to apply power on corner exit." So sharp turns would quickly lock up the inside wheel listing traction and braking power way too soon. Less lock more traction more deceleration in less time win.
