Greetings contestants;

Because of the large number of potential hits for some of these,
I have deleted all but the "best fit" results.

I don't quite know how to judge the winner here. By strict interpretation
of the rules, Canie and Petra have the only hits on April 1. Canie's is a
perfect date fit, Petra has the larger magnitude.

Widening the window, Don has the lowest probability hit.

Lowell, it's your egg; you call it.
