Regarding the bomb plot at the very bottom. Examining the number of bombs dropped in each square and comparing it to the Poisson distribution, it appears that the distribution of the bombs is random.

But looking at the plot on the map, it appears that the higher incidence of bombs is focused on a specific region. The Poisson distribution doesn't account for the fact that a lot of the squares with a high incidence of bombs are adjacent to each other. From my layman's understanding, it appears that the bombs were in fact targeted on a specific area, but that there was a random offset from this area regarding where the bombs actually landed. Because of this, you'd see randomness in the distribution. But the distribution of bombs wasn't really perfectly random.

Is the author deliberately avoiding this point, or is there something I've misunderstood?
