Wow....I mean, just...wow.
Like most folks I have my own field of expertise & it's not mathematics. Reading through that thread certainly gave me an appreciation for the those who crunch numbers.
Honestly, JZS, it sounds like you take SJC's arguments & post them on a board somewhere, then return with the comments made by people to try and debate him. From an outside observer you're writings look muddled.
SJC, I'm still reading through your myriad explanations of things numerical. I think you've done an excellent job of explaining the base problem in utilizing the XOR function. I doubt you'll convert any true believers. But I can tell you that your explanation made sense to at least one non-math type.
A short-live side thread was interesting as well. Claus Larson showed how they pick & choose data:
[Paraphrasing Mr. Larson]
During the Indian Ocean Quake Mar 28 2005, they chose to begin a little more than an hour before the quake, using an 8 hour period.
During the Western India Quake, on January 26 2001, they use a 30 minute period, starting 15 minutes before.
During the Earthquake in Afghanistan on March 25, 2002, they use a 4 hour period, starting half an hour before the event.
During the big tsunami on Dec 26, 2004, they chose to begin half an hour before the main quake, using an 8 hour period.
The argument that was used was "it's like focusing a lens".
As I stated before I'm certainly no math whiz. But I like to think I'm a fairly intelligent person. I can pick up on a lot of patterns.
I don't see how going from
60 minutes before for an 8 hour period
to
15 minutes before for a 30 minute period
to
30 minutes before for a 4 hour period
to
30 minutes before for an 8 hour period
can constitute 'focusing'.
