Over at DSL Reports, we have a site with that lists people's crunching speed by processor & operating system. People send in either SetiSpy logs or setilog.csv files and we complied lists. One of the by-products of that was the Best Reurned Item page (
http://www.ameri-becca.com/returned.htm). It shows the highest number of returned items (spikes, guassinas, pulses, triplets) and the best score/power for each. Best for guassinas, btw, is 24.
