Like with a carbon paper

We were supposed to start for the C1 but it was like at Shisha Pangma - a carbon paper copy. When we woke up in the morning there were lots of snow in the ABC and the snow fall continued on. So we postponed the start by one day. Anyway, the weather forecast from the USA clearly said that the best days would be from May 15 through 18. The French stationed a bit above us confirmed it with a forecast from their best meteo station. Well, with a slight difference the best summit days should last until May 19. In that case one day lost shouldn't be a problem.
