According to BEA, "the descent lasted 3 min 30, during which the airplane remained stalled". Since the descent actually lasted 3 min 22, that means the airplane stalled before reaching its apogee of FL380. I use the word apogee because that part of its trajectory was partially ballistic at less than 1g. My tentative trajectory confirms that.
