SETI@home Weekly Update

June 16, 2000 - Dan Knight

Because last week's report had to wait until Saturday, due to a lack of updates on the SETI@home site, this week's figures cover a six day period. This week hasn't been much better. What figures I have come from Dave's Stats, since the SETI@home club team page hasn't been updated since Monday.

This week one team joined the Top 25, one moved down a step, and Team Quebec dropped off the list to #26.

Changes are color coded: red text for hot teams that have climbed in the standings, blue for those that have cooled and dropped in the standings.

Team 6100, the slowest part of Team Mac Observer (it's only for unaccelerated Power Mac 6100s) has grown to eight members. We've now completed over 50 units and are averaging 12 units per week.

Key tools in this anaysis are the SETI@home team statistics page, the SETI Checker program (which visually graphs recent weeks for team performance), and Dave's Stats, which cover the whole SETI@home project, as well as the team he's part of, The Knights Who Say Ni!

In the following analysis, data in the second column comes from the SETI statistics page. Information in the third column comes from my analysis and Dave's Stats, which is my source for the average recent work units per day (because the stats have not been updated since Wednesday, we're using Wednesday's averages). Note that this is a volatile figure which can change a fair bit from day to day, especially as members join or leave a team and bring their work units with them.

You can also view weekly reports from April 14, April 21, April 28, May 5, May 12, May 19, May 26, June 2, and June 10.

Remember all this is based on a fairly simple mathematical model that is thrown off by significant defections or additions to a team's stats. Dave and I have been corresponding to develop a model that will create more reliable predictions.

That's how the top team standings look this week on the SETI@home club team page. Come back next Friday for another update. (And if you'd like to join a team, I'd like to see you join Team Mac Observer.)
