It has some interesting dips that seem to be testing some form of sudden dip in altitude which could be seen as related to the system under scrutiny, a safety system designed to prevent stalls which could in some cases "send the plane into a fatal descent if the altitude and angle information being fed into the computer system is incorrect" (not that any of this confirms that the MAX has issues or this is what they were actually testing)
