specs for control pressure regulator (warm up regulator) pressures at cold temps, MC engines

In my ongoing effort to debug my ailing 200qa, I measured the control
pressure at cold temps. Does anyone know what the specs are for 30 degrees?
The Bentley and the Alldata only give the specs for a narrow range that
starts at 68F.  I measured 20 psi, but if I extrapolate the Bentley/Alldata
curbes, I should be closer to 10psi. Is there a spec?

Thannks everyone
