Hi MoZTelstra,
Due to Heater Profile has 10 temperature points, gas resistance will change randomly, not like other modes, which only have one target temperature. As so many target temperature, the sensor will heat and cool down continuously, at the same time, gas resistance will be measured, so which will be a little inaccurate. Usually, it can only detect the kind of gas in HP mode, so in this mode, gas resistance only be considered as a whole trend, it's meaningless if it concerns just one index in 10 indexes.
