Hi everyone, could you help me understand why my Gozney Roccbox cannot reach the temperature claimed by the official preheating time?

In my area, I’m using a 28mbar pressure regulator and a propane-butane mixed gas. However, it does not show the pressure value for the mixed gas.，After preheating on maximum flame for 15 minutes, the stone temperature is only 310°C, while the official one has already reached over 400°C.
