I have a hard time believing that #2 would be 25% loss and still be fairly close in compression to the other cylinders.

It can happen. Compression is rather confusing.
While you are doing your next leak down test look for the leaks. If your coolant is bubbling, then you know what to look for. If you are hearing a hissing through the exhaust or intake then you have a burned valve.... You know the drill, find out where this leakage is present. It will tell you a lot about your engine.
