  Classical, Quantum and Relativistic mechanics elect time and space as
fundamentals, extracting the measure of motion -velocity- from this static
space-time platform. Conversely, the timelessness of Statistical mechanics
computes the physical flow as an evolution of (dynamical) states which, at the
end, comes to be what would be denoted as time. Moreover, the general structure
of mechanics is such that the notion of observability is mixed up with that of
measurability. In such a context, ignoring the distinction between "observable
entities" and "measurable quantities", and projecting dynamical objects on a
static background, the measured value of physical entities is taken as the true
or real value of the entity. This contribution emphasises this distinction,
correlating the concepts of "real values" and "experimental values" and
indicating that motion is always underestimated in the spatiotemporal platform;
following a gauge transformation, an argument centred on measurability favours
a relational "non-relativistic" formulation, with potentially analogous
predictions.
