Fair enough Danny, I guess it has gone a bit off topic, however the resulting topic is far more interesting then the initial question of the qnh.
Yes it is a bit over the top in some respect. But then again if you had an old ATIS (which is not unlikely with them changing every 15 minutes) at least you have the latest qnh. I personally cannot be bothered always to recheck the ATIS to see if it is still few at 1400 or now few at 1500. This is all offcourse assuming itīs a nice weather day, because obviously on a bad day I want the latest!
