The intention is to show some of the literature that was around at the time the H-P slot was invented. The table dates back to 1933 so, of course it predates the NACA data, but it was the type of material that would have been available at around the time that the Bf 108 and 109 were under development.

What I should have asked is at what combat speeds were slots effective? The data shows they opened at speeds ranging between 90-120.5 mph, but I doubt that a 109 in combat slowed to those speeds.
