Maximum lowness on the street is not your supreme goal.
On the street, you want to set the ride height to being in the window of minimum camber change as the suspension cycles up and down. Then control suspension movement to stay in the window for as much of the time as possible.
Typically, this window will be fattest when the LCA is about level, but actually when the LBJ is level with the Pivot pin on the other end.
