They know how long the transient low-level indication lasted --
according to AW, the low-level indication had already gone back to normal
as the engines began their power-down.

Why not say "Our low-level sensitivity is too great" and add a requirement
that the indication must last for T+delta milliseconds before the engines
are shut down (where T is the transient duration, and delta is some
reasonable fudge factor that takes into account the amount of fluid
remaining in the system when a valid low-level indication is detected).

There's a bigger problem here than timing (and we're talking seconds, not
milliseconds). The LOx line cavitated. That is not a condition under which
you want to run your engine. Boing is going to have to find out why the LOx
behaved the way it did. Patching the problem with time delays is not the
answer - that's a band-aid. Everyone knows band-aids don't stay on forever,
and sooner or later that particular band-aid will find some way to come back
and bite you.
