Yes of course, just as a jib acts as a slat on an airplane wing, keeping flow attached at higher angles of attack by bending the airflow more sharply, so a assym spin acts as a 'super' slat bending the apparent wind around even farther.

But consider the context of this thread. The guy is a new sailor on a Prindle 18. Now I don't know for sure, but I'm betting he does not have a spinnaker. He has too much weather helm sometimes. What would you bet it's that he keeps the traveler centered all the time, which is the wrong way to sail his boat as equipped?
