Saris Fluid 2 Power Curve

Most ppl talking about power curve for Fluid2 talk about the older version branded Cycleops. Is anyone using a new one? I would like to know your zpower experience and how you adjusted the knob (2.5 turns after it touches the wheel). It seems the resistance is larger than what I would expect… Anyone care to share how they find their numbers with this trainer following the guidelines 2.5 turns? Did anyone try 2 turns for example?
