I was at the point with 4 (normal) ravens and a Noctis that I could blow up missions just about as fast as I could fly through the gates/rooms and I never saw the return some folks are claiming from anomalies/5's. For that matter, I never saw the return people were claiming from chaining 4's either. Then again, I suppose these folks were flying the exact right missions for the best drops/salvage to make the highest-selling items and had manufacturing options that I didn't have, which I'm sure isn't a trivial difference.
