Is the locking effect linear or non-linear as you lower (power/coast) ramp angles and increase locking effect? It explains that the clutches are linear (8 is twice as much as 4) but does 25 degree ramp give twice as much locking as 50 degrees? Numerically obviously, but my reading suggests diffs don't ramp up (excuse pun) in a linear way. Or does the programming just compute it in a linear fashion for simplicity?
