I just did a new bind test by starting with my pre bind rig and geo, removed all my facial rig joints and then skinned my mesh just as in the Emma tutorial. I only took the time to adjusted the neck weights and then tested the head control rotation. The results where actually worse leaving the eyes even farther away from the correct position. So I must surmise that something else is effecting to proper movement of the eye geometry.
