at less than 200ft MSL, then the MP indicator with the engine at rest (and
sitting on the ground) should read the approximate value of the barometric
pressure or about 30in

Out here (2200MSL) the MP indicator would read about 2 inches or more lower
or about 28in (or closer to 27.5in) MP before engine start
