I tested the compression 3 months ago, and the leakage a few weeks ago. When I tested for leakage, I warmed up the engine, then shut it down, and pumped 100 psi into the cylinder at TDC and the pressure dropped to about 96psi. I couldn't hear any air escaping from the intake, exhaust, or the oil fill tube. Im using the APC with a knock LED to detect knock.
