Small bus, but a still a bus.
I have had several (individual!) failures in flight that should have led to Rev being inoperative on one side. Now previously I would have only pulled the one reverser, but since the update came out we have been selecting both reversers anyway.
Guess what - On 4 out of the 5 times this has happened since the change, I have still achieved reverse deployment on the supposedly failed reverser. Obviously, if reverse is locked out then it isn't going to happen, but if its only inop on the status page then its worth a try.
