What this is saying is you need both of those springs in the gate to make .5 bar be your opening pressure. The chart's lowest single spring it lists is in fact NOT the smallest spring available from tial. This make sense? If you want the smallest possible you want to use just the small green spring which is .2 bar for the MVR and ~2.9 psi.
I called ATP Turbo to order mine and thats what they told me was the lowest spring pressure the make for the MVR s a 4.3
