There was just one earthquake which had a listing for all 3 test times. The rest had listing for either the first and second times or the second and third times.

In nearly every case, for the second and third times the values in the second and in some cases the third column went up for the 2004/08/22 listing.

Example:

07/25 91: 95: 1992/06/28 11:57:34 34.20N 116.40W 1.0 7.6
08/22 96:100: 1992/06/28 11:57:34 34.20N 116.40W 1.0 7.6

The fact that nearly all of the earthquake pairs showed an increase for the 2004/08/22 listing probably means something. But I do not know what it might be. I cannot think of a bias within the test which would cause something like that to happen.

Basically what is appears to be saying is that between 2004/07/25 and 2004/08/22 almost all of those California area earthquakes showed increased values versus all of the other 5.0 and greater magnitude earthquakes which occurred around the world since the beginning of 1990.
