With 0 hours of track time I disagree.

But from obsessing over the drawings, photos, etc. my conclusion is that when engaged, the clutches (be it 10% or 100% or whatever) will lock the center diff. at 50/50 until some differential torque (ie. loss of traction) between front/back overcomes the clutches at whatever duty cycle they are being driven. I do not know what that torque is.

You can get more than 35% at the front wheels - it will be 35% of the total torque plus whatever torque it takes to overcome the clutches (well sorta). And vice-versa for the rear too. This is described by that table "Here is a table that summarizes this:" in the DCCD FAQ article linked. Note the torque to the rear is more that 65% when the clutches are engaged (and this is an extreme example where the front is on dirt and the rear on pavement).
