That's not necessarily the case, Bellman.

Remember, its not just what the arrays can physically pick up, but also what their computer processors can resolve from the raw sensory impulses hitting the physical collectors on the array.

So contacts on the extreme edges of their apparature maybe making a physical impulse on the sensor surface, but the computers may not be able to make a sensible datum from the physical effects at the sensor surface.
