(Cue Brit car jokes here...I would, but I'm just feeling lazy today... )

I wouldn't worry about it either as long as the compression is not leaking out of an exhaust valve. Did you listen to where it was leaking? You'd hear it leaking into the exhaust (exhaust valve), intake manifold (intake valve), or case/valve cover breather (rings).

It's most likely going out through the rings, though.
