Your stall speed varies with gross weight (and associated g loading), rate of change of airspeed, center of gravity, and prop wash over the wing (i.e. power). The speed you stalled your airplane is unique to those factors. To calculate your true stall speed, you need to use a different method than the one used to calibrate the AoA (refer to EAA Flight Test Cards).I just completed the stall/AOA calibrations for the 4 different flap settings on my RV-14A. I was surprised to then find out Skyview doesn't record or display the airspeed where each stall occurred.
I wish Skyview would indicate the stall airspeed values for each flap setting (Vs, Vs1, Vs2, Vso) on the airspeed indicator tape as it does for the Vx, Vy & Va performance speeds. Having these real-world numbers would create a great reference I could then add to my POH.
I am curious about what 4 flap settings you programmed on your 14. I only programmed full up, half flap (approach and shortfield takeoff) and full flap (landing).
