I am sure you know that I know that. I just don’t see the relevance of that to your argument. I understand the quantizing part of your argument.
The fact that the hardware may not have a bandwidth of half the sample rate is not relevant to the request (at least the requesters take that view).
Why were “measurements” in microseconds put in as a feature in the first place? Was it a total mistake?
Here is another request (though in this case the user wants four decimal places for seconds): Fractional millisecond time readouts .
