Have to agree with Paul in that your in a continuous decaying speed situation and need to be very specific about what phase of the landing. Per the poll you can only pick one number. I was taught that in a mythical perfect landing you stall the plane an 1/8” above the ground. The only exception being a wheel landing. Rarely happens for me . Certainly could be exceptions for some types of planes. . I wince when I see nose wheel planes landing on all three wheels at once with almost zero angle of attack. Poor technique in my opinion.
I pulled data on 150+ landings in my RV-10 over the last year on IAS at 50 feet and at touchdown to provide some empirical data. The graphs are attached below. Obviously, these can be swayed one way or the other by conditions of the day, loading, etc. Viewing it as a range and histogram to give directional guidance, not anything down to the knot.

There are numerous threads discussing AOA here on VAF. Learn how to do a search for them and you'll see. Also, many of the kits that Van's sells have a tab-type stall warning buzzer, and that's a single-point AOA.
