What are the factory compression gauges displaying? kg/cm^2? bar?

Anyone with knowledge of leakdown numbers on a rotary? Numbers on my friends 12a(my old car) were scary low...(high leakage). I want to assume that since the rotors are not spinning that the apex seals are not sealing as they would while running...where as a Pissed-on motor's rings will seal very well while static. Any logic to this?
