The plane got down to a low altitude quickly. The mask worked "good enough" in this circumstance, but that is only one piece of data that the "mask works fine" as designed.

The masks are designed to work long enough for a depressurized plane to make an emergency descent. That's their one job.

Proving the safety briefing is an unnecessary waste of time. Everyone did fine, except for the poor passenger who was seated by the window.
