The up and down lines, the green one is at .012" lift and the blue one at .004". The graph lines are the brown ones. The arc looking one is the valve lift curve, the other one is velocity. Between the green and blue lines the velocity curve is constant at around .0005" per degree. I assume from this design, Porsche expected to see a .012" hot lash when the engine was warmed up and making power.
