I don't think he has modelled it incorrectly, I don't understand the confusion. Prop Pitch is just RPM. 0% Prop Pitch is coarse pitch/minimum RPM, 100% Prop Pitch is full fine/max RPM. What's the problem? I have mentioned this several times already, you control the RPM governor, not the pitch directly.
If you're trying to conserve fuel you just turn down the Prop Pitch to about 75% or something. For economical flying, for example, the Spit IX manual recommends flying in the lower MS supercharger gear at the highest obtainable boost for that altitude, up to a maximum of +7 lbs/sq. in., and reducing the speed to 170 mph using the RPM governor down to a minimum of 1800 RPM.
