I believe I've also heard that you can do a test, then add a little oil to each cyl and test again. If compression goes up with the oil, then that shows that it's the rings. I've not done it myself, it's just something that I've heard. It makes sense, but I don't know if it has merit or if that would be the case for any engine bad rings or good.

Do you know what the engine SHOULD be showing?
