Merlin negative G cutout too quick?

[Crumpp]

I would like to know now if the cut out was an either on or off event with nothing in between.

Yes cut out is a cut out.

The onset is depending on the Onset Rate...

At typical ROR acceleration onset rate of 6G/sec the Merlin as tested in the report cuts out in ~1/6 of a second.

In the cockpit, that would be instantaneous.
