the biggest one was that the Rs factor was used incorrectly: instead of "surface volume of gas per volume of saturated reservoir oil" it is defined as "surface volume of gas which a volume unit of surface oil dissolves at reservoir pressure". Besides this, there are a few smallish improvements like the oil density being a function which can be called without having the boilerplate objects (i.e., the fluid state and parameter cache objects) instantiated.
