6000 random dates in 100 years is also erratic and gives a similar answer; the distribution does not fit the expected line.

Further tests with larger samples shows that the distribution converges to the average with enough cases. VERY large numbers.

Smaller sets just don't work. What's important is the pattern; are certain angles found more often with quakes and the answer is no.
Different samples give different answers.
