Ok, thanks. Just one last hypothetical question if you don't mind:
You are on descent to YMON (middle of nowhere) after very diligently calculating, through linear interpolation, that the Forecast Terminal QNH will be 1011. It is 2.06 am and ATC let you know that there has been a METAR issued for YMON, automatically generated, issued 2.00am. QNH now 1016. What QNH do you set through transition?
