OK.... doing some of my own calculations...

ANSS catalog 1-Jan-1980 to 6-Oct-2013
6.5+ quakes

Found 1261 events.

12333 day span.

That's 12330 three day windows.

That's 1261/12330 = .102262590219771

So that's about a 10% chance on any given 3 day span assuming a Gaussian distribution.

I have not yet calculated actual hits given the database.
