i would think we hopefully won't take that SOA response literally. i'm guessing it holds the 90/10 ratio fixed until some threshold if slippage is noted and then the adjustment takes place.

of course, i have no clue if that is really the case, and also since this is my first AWD, i really am just speculating because i like to as a scientist (which i am for my profession...just not an ME or auto industry scientist! )
