For the Poisson distribution the interest is in a random variable, X, that represents the number of occurrences of an event within a fixed time.
The linear correlation observed when the number of positive samples remains below the limit of 30% coincides with the Poisson distribution being nearly linear in this range.
1 and 2 correspond to regions of space passing the Earth that have preferred/discrete velocities, and not random ones, as randomly distributed velocities would result in a Poisson distribution, i.
