    Everything I’ve read suggests the thermometer is measuring group head temperature at the start of the shot and water temperature about 10 seconds in.

    There is no water in that chamber prior to the shot starting. As the HX water flows into the portafilter it is now influencing the sensor as it flows past.... and is giving or taking heat from the great lump of brass it is flowing through.
