Well as I told some friends here at sp, I never stop to acclimatize first, I'm one of the luck bastards about that, never had any headake, altitude sickness, nothing but frostbites, and all of them well taken care of.
The thing is, the "X" factor never help us, the so called "weather conditions", and that my friends...that is our most feared enemy.
The result: Quit on the first attempt at 5.240 m just bellow the glacier line, and at the second attempt, never got the chance of leave the refuge. Terrible weather. At those two days, no one summited Cotopaxi that I know of.
First attempt, around 55 photos and some videos;
Second attempt, ONE video, that's all.
