I think you might be applying an oversimplified assumption the
situation.   Noise limits the capacity of a channel,  and increases
the number of gyrations required to encode a bit, so that it can be
received without error.

The degree of 'random noise',  'actual latency variation',  and
'natural packet ordering'  can be estimated, to identify the noise.

Even with noise, you can figure out,  that the  average value which
the errors were centered around increased by  5ms or 10ms,  when a
sequence of packets with certain sizes,  certain checksum values,  and
certain  ephemeral ports  were   processed in a certain sequence,
after a sufficient number of repetitions.
