You are the one that stated the 30% more fuel efficiency, not I. Are you now saying CRJ9 is not even 15% more fuel efficient. You are only contradicting yourself. The thrust rating is for the NextGen Enhanced version. If I am wrong then the instructors who told us those figures were wrong.
Now get back to the original question.
