While of course grade A is the best for us, I believe grade B should be also considered by us, if we can make exact sense out of incomplete rules.

Of course, if someone wants to analyse grade C notations (and I believe BEAF belongs there), we cannot stop them, but I don't think this should be one of our main concerns, as there is no "real truth" to them.
