Michael;

Every user will have a different idea on this so here are mine.

I would prefer one line formats as in Excel spreadsheets for ease in computer reading. Consistency is vitally important, otherwise I have to edit by hand which can introduce errors.

For online access, the ability to sort and select is important. The user may normally want to see all predictions by a given individual but another user may want to see all predictions for a particular area or a certain time or even a certain magnitude range.

The probability was originally intended to be the predictor's calculation of the chances of the quake happening. Others have used it as a measure of their confidence in the prediction which always struck me as odd. Why would you even make a prediction if you weren't sure of it? In any case, I make my own calculation as it's a critical part of determining significance.
