1980 911 SC Commpression test Ranges

Engine

Vehicle Information: Model: 911SC; Year: 1980; Body Type: Coupe; Total Mileage: 58000;

I had a commpressionand leak down test down on a car I was looking to buy and the leakdown test came back 3% on all cylinders and the compression test cam back @ 200PSI. The mechanic said that the compreesiontest was a little hight because the engine was stilll very warm. Is the correct??
