I cant give you figures, but I always thought the aim was around 4 degrees, at the vent.
That is what I have always observed from a fill, and on TV.
The central vent is different to the outer vents. The control knob function, (the one below the clock with the blue circle) allows you to bypass the heater(or air con) and let air from outside the car. Why, it helps to keep you from drifting off when you have the ATC set to relatively warm temperatures. That is how I understand it. I am not sure if it is set to the grey circle,that it will put out air con air (if that makes sense), but as I say, switched to blue, it will give air at roughly ambient outside temperature.
To check the temperature of your air conditioning, I think it would be better to place the probe at one of the outer vents.
