Re: [QuadtoneRIP] If .quad files hold 256 values, how can they convey 16-bit data ?

Are we confusing precision with accuracy ? We all know that we can be precise to 10 decimal places, but if our readings are only accurate to 2 decimal places, our data is only good to 2 decimal places.
It seems that we are starring out with readings from a 21-step wedge, then smoothing them out to 256 steps. At that point, the graph may be smooth, but it's still accurate to only 21 steps (less than 5-bit precision). smoothed out to 8-bit precision. Apparently the 16-bit driver subsequently interpolates that out to 16-bits.
We could interpolate it to 64 or even 128 bits precision if we liked, but that's just precision: the data is only accurate to less-than-5-bits, no ?
I scan film and presume that my 16-bit files are actually accurate to 16-bits, not just interpolated. Am I mistaken there too ?
