Flaps-up was commanded about a minute after take-off, which seems about right. The AGL altitude of the plane is hard to determine from the graphs as they only list pressure altitude. It's a high airport with, I believe, rising terrain. I'm not sure if the 1000' AGL cited is supposed to be at first MCAS engagement, or the last one, or at some other point in between.
