The B model Piper Aztec offered optional 22 gal tip tanks of a different shape to the standard wingtip. It was said they were Hoerner wingtips. With these Hoerner tips the Aztec would land a few hundred feet shorter and cruise 5 mph faster. Similar but not the same as your Chamfered tips. The Aztec had a non tapered planform and thus was full cord at wingtip, this may have exaggerated the improvement. The comparison Aztec was a C model with standard round planform wingtips. Old memories.
