I am sure they ran some sort of simulation first.

However, "the right engine inlet's automatic control system malfunctioned".

That probably wasn't part of their simulation. While it sounds like they could have erred on the side of caution and cancelled the remaining tests after that occurred, they must have been confident in their manual control abilities.

Even if they had simulated with the inlet(s) under manual control, real life airflow and reaction times are going to vary.
