I have to agree. My leak down tester is my least used tool. It has been several years since I used it. If you have say 30% leak down in a cylinder and the car runs fine, what are you going to do, tear the engine apart? If you have a low cylinder and want to know if it's rings or valves, you can do a wet test or even use an air hold like you would to do valve seals. Just listen to where the air comes out.
