SETI@home Weekly Update

June 10, 2000 - Dan Knight

The update is a day late this week. Sorry, but SETI stats were not updated early enough on Friday, and then I had real problems with the cable modem.

Again this week, eight of the top 25 teams changed places.

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 48 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, and June 2.

This week, nothing below the Top 25 looks to be moving into the Top 20 in the near future.

Possible future contender for a Top 25 spot:

• Forum Hardware.FR Team, 28, will reach 20, according to Dave's stats. They have the 6th highest average units per week (1,740) and could reach 20 within a month.

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.)
