Seems consistent to me.
Apart from the altitude issue, that's with the speed? Close to 400 kts less than 1000 ft AGL seems excessive.
That is an interesting point. The Lionair went pretty fast too, as they got a stall warning and probably wanted to add more margine to stall speed be on the safe side as the stick shaker went off.
Maybe not a MCAS-event, but false stall warnings. The Lionair had the stall warning going from liftoff, the MCAS problem only kicked in when the flaps where retracted. at 1000 feet agl, wouldn`t the flaps still be down, so no MCAS problems? Ok, 400knots is probably not the speed to have flaps still down.
But at a high elevation airfield with high ambient temps, if you get stick shakers, you probably hesitate to climb further, as climbing is not a good idea if you are in a potential stall approaching flight regime and you are running the unreliable airspeed checklist?
So it could be like this: bad AOA-unit/pitots, stall warning at takeoff from high alt airport, cautious to climb running UAS checklist, adding speed to migitate the potential stall issue and approaching high terrain without willing to climb due to stall warnings?
