The stats screens should focus on recent client performance. Daily. This way teams/individuals want to kick ass every day. It's not very exciting to put a bunch of machines online, and have to hunt and hunt and hunt for a statistic that you can actually see you're doing good at.

For instance. Based on daily results yesterday, my team was #55. Based on every other statistic we're getting the crap kicked out of us.

It's not as fun bringing on new machines, when to show off, we have to tell someone to click here then there then there and then explain why it says we're ranked 1547, when that day our perfromance was really #55.

In summary. The ranking system if optimized to rank people by what they're DOING instead of what they've DONE, will keep everyone especially the big "DONE" guys attacking. No resting on laurels.

Competitiveness and acquisition of significance are 2 of the most powerful short/mid term motivators in distributed computing. Whatever can be done to leverage those attributes will GREATLY add to the acquisition and participation of exisitng and new crunchers.
