Only later was the reason for the Davis wing's performance properly understood. Largely through accident, the shape maintained laminar flow further back from its leading edge, to about 20 or 30% of chord compared to the 5 to 20% managed by most airfoil sections of the era. Although later designs greatly improved on this, with some maintaining laminar flow to upwards of 60% of chord, the Davis wing represented a great improvement at the time.
