Active missions are excluded from the success rate: a live mission has no outcome yet, so counting it would report a rate the records do not support. 0 of the 1 record are still active, leaving 1 concluded. A partial success is a distinct recorded outcome, so it is not counted in the numerator, but it stays in the denominator.
