On the other hand maybe not. I guess I was looking at the top of the cap.
I think what happened was I was looking at something from the top of the cap and I saw the mud shooting out and I did not realize that it was the top, not that the bottom had blown off yet and was leaking. So perhaps it has not blown off yet, but clearly we can only take wild guesses as to if the leak is problematic yet. And now it does seem to be coming out at a rather scary pace.
