I don't think it's realistic at all to expect linear relationships between anything, given the complexities and interactions of the various processes - just look at a Brayton cycle graph for starters. Then, everything involved is mostly following a square or cube rule, some power consumption will be fixed, some variable. Forward speed versus stationary, IGVs, Bleed Air Valve thresholds etc etc
