Amit;

Good news.

The odds on a 6.5+ quake on a given day are 11%

Selecting a 1 day window based on the moon trigger date gave 26 predictions with 6 hits.

That's a significance level of 94.1% so you're doing good.

However, that's a small sample so I'll need to extend the testing time range.

It's also rather useless, getting only 6 hits in 10 years with no idea of location.
