For max power, most people aim for around 180-200C
For min power keep it above 140C to avoid cold burning, which leads to soot build up eventually.
Certainly how cool the incoming air (to be heated) does impact the body's temperature as that airflow is cooling the body, to obviously extract the heat it is producing.
However the BEST way to gauge proper combustion is to confirm that CO is low from the exhaust. That shows the correct air/fuel ratio is in use.
Sadly one of the most unreliable parts of these heaters does seem to be the body temperature sensor.
The most common symptom being people finding their heater is running the fan when it should be off.
The sensor has lowered in resistance, and makes the ECU think the heater is hot, so it enters a cooling protection mode.
Whilst in this state, the heater cannot be started either.
So yes, readings can be skewed if a sensor is on the way to failure.
