I can also say that I've never seen anything on a "good" motor worse than 5%, but I've got an S2k in the shop right now that is running well at about 20% leak- just down on power. It's turbo and was making 320WHP at 9psi 6 months ago, after a detonation issue (bad tune) it's only making 270WHP at 11psi.
20% is pretty bad and indicates a significant problem. I would be concerned with anything over 10%, though the car will probably run for a long time like that.
