First 911 please help with compression/leak down numbers

[harv666]

Looking to buy my first 911, its an 83 911sc Euro/ROW. 129,000 miles. Theres a lot of good about this car, but then theres these compression and leak down numbers and I don't know how to read them properly so I'm reaching out for help from the community. The car really hasn't been driven in the last year. This was done today. Any help is much appreciated.

The numbers read like a tired engine. Though the leak down numbers seem high compared to the compression numbers.

Did you note where the leakage was occurring?

Has the engine been run a bit since sitting, or just fired up and tested?
