Roger,

OK. Thank you for correcting me. I was a little confused because you had been attempting an evaluation of Don's predictions, even though the probabability values were not equal.

"What I will do is plot predictions and quakes to show the process visually."

Yes, I noticed the thread with Chris's suggestion to Glen and you picked it up. It might be interesting to do visuals of Don's predictions too. (And even of your favorite syzygy predictor.)

A picture is worth a thousand words, they say. Animation even more.

The main thing I noticed in your proposal to Chris is that you will make the animated quakes strike in proportion to real time duration. That would make a fascinating animation, even without any predictions thrown in.
