Yes, from all I have read that is true...
with the caveat that ' hot' coming out of the evaporator means well above the ambient air temperature being blown across the evaporator fins...
And
that there is a range of 'fully extracting' the cooling potential of the refrigerant being sprayed into the evaporator which will be reflected in changes in the vent temperature but which would not cause the need for physical changes to the position of the Txvalve for the reason stated about its Constant ' seeking ' type of behavior .... thus a mistake in judging and applying ' correction ' to the Txvalve in the wrong direction ( easily the result of reading the results at the wrong time in the constantly changing cycle ) would be catastrophic in its effect upon the compressor... slugging it with liquid refrigerant.
