What would you have done blew out your knee up high or you had 5 symptom AMS and could not move and were stuck overnight?
Temperature does not have as much to do with consumption as people believe. There are other factors; such as, exertion level and humidity. The most water I ever drank on this trip was on the coldest day I reached the summit...as did everyone else in my group...we all went through about 5 L on that 10 mile trip, thank God for snow.
You should have water left over when you refill coming off the switchbacks.
The name of the game is safety here, not time or pack weight...especially this time of year.
