Speaking as a devil's advocate, could the war have skewed teh 1941 data?

Doubtful. The "counts per observer" would likely be higher in 1941 as a result (fewer, more dedicated observers, more opportuities each). Remember also that count was taken immediately after Pearl Harbor (the count is currently taken from December 14 to January 5).
