Barnes McCormick's text, Aerodynamics, Aeronautics, and Flight Mechanics, has information on slots, slats, leading edge flaps, and Kruger leading edge flaps on pages 113-120.
Slots can provide a CL increment on the order of 0.1-0.2
Slats can provide a CL increment on the order of 0.9
Leading edge flaps and Kruger leading edge flaps can also add an increment of about 0.9.
A Kruger leading edge flap combined with a split trailing edge flap can give a total CLmax on the order of 3.0, which is about 0.3-0.4 higher than the leading edge devices acting alone.
