Merlin negative G cutout too quick?

It does not mean that at the location of the carburator it was 0.1g. And also the acceleration at the carburator in plane x will be different to the acceleration at the carburator in plane y even if the cockpit instruments reads the same acceleration for both planes. This is due to different location of carburator with respect to centre of gravity of the plane.

Of course you're right but don't forget that in flight the Pilot is the reference : he fly likes he feels and act in concordance.

So if it might be interesting for the engineer to get the true acceleration on the carb float, as a flight safety rule, it seems logical that they hve measured what a pilot would feel.
