How does the side taper of the boatail affect the 4 degree limit? The red/blue drawing above shows a 2 dimensional vertical taper, but a boattail that tapers both vertically and horizontally is going to require less airflow to fill the void under the boattail than a boattail that only tapers vertically (as shown in the drawing).
