Well, in theory yes, but you should account for the fact that even on a perfect engine, some loss is inevitable from the rings and valves. It could be really low on a high-tolerance race engine, or on an engine like say a 40's era Ford, could be like a 5-10% loss! If you check it on a day before, during or after a storm, it might appear be low because of barometric pressure. Tons of stuff can result in lower readings. 130 seems alright for now. It might indicate tight valves.
