I'm not disagreeing with you. I was just pointing out that since engines are now more reliable that is why we have 2 engine ETOPs. Boeing must have used the same reliability logic to get the FAA to approve thrust reversers included in the landing data. IMO the logic is flawed, but is th only reason I and some of my co-workers can understand why it occurred.
