Merlin negative G cutout too quick?

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.

For the document you are right, but unless I am wrong we discuss the carburator and its behaviour here so I think the acceleration at carburator location is interesting. That is why I said the cockpit reading cannot be transposed 1:1 to the acceleration experienced by the carburator.

My thesis is that the acceleration experienced by the carburator can be slightly different for different plane types even if pilot acceleration is equal due to distance differences between plane cog and carburator. I cannot tell however how big this difference could be (basically I do not want to make the calculation ).
