New to SETI and question

Hey, I just started using SETI and joined the overclockers team. Just a quick question...how rare are results such as these:

Spike Power Score Signal ratio Resolution Frequency Time Drift rate
Best score 1.58592642396735936E20 18.598 1.98240802995919904E19 0.075 1420743712.78 73.82 -7.9690

Using Seti Spy your statistically interesting signals will show up with an * next to them and will be displayed on your sky map as a green dot.
