Your figures are very accurate and believable for representing average difference between stock pick of these models.
Little discrepancy may be there as everyone has different tyres and rims (rolling resistance and unsprung mass), condition and grade of oil at time of test, slightly different ecu map (compensation for variance in sensors, dirty throttle body, dirty cat con etc.)
Also, the person making video didn't know that all speed runs are to be done in both directions taking average of both directions to compensate for any inclination and direction of air.
