I recently discovered this site, and joined tonight. Its fascinating to read your predictions and watch what happens. I don't mean to be rude, (not sure what's considered rude here!) but how do you do it? How do you come up with your date windows? Are we talking educated, rational thought, atmospheric or cosmic influence, geological events, luck..... or what? Whatever combination of input you're using, you seem to be onto something. Best of luck whereever you end up.
