If I may make an observation regarding the perceived lack of competition because of folders distribution, might I suggest that the contest is made more fun by the effort to try and recruit other folders into the contest once it is running? I am the only non-evga folder to join the contest but there has to be others out there who if they knew that the contest is running would join in. Also, the requirement to change the team you are folding for also acts as a detriment to recruiting outsiders. If you really wanted to open it up, you'd make it open to anyone on any team and find a way to allow folders to join even a the last moment to allow mid contest recruiting.
Also, as an option, you might consider introducing a handicap system where folders that produce over (400k PPD?) begin to get handicapped based on how far over the cap they go. Their extra points would still count but to a lesser extent so that the little guys are still making a difference.
Or run two tiers of contest at the same time, the first contest only counts the bottom 400k ppd of each person and the second keeps track of surplus production. That way a team with many folders below the cap could win one contest while a team with a few folders way over the cap could easily win the other. Perhaps a third contest could be done at the same time counting how many WU a team completes and then the true winning team is the one who collects the most victories between the three possible wins. This would require a team to decide how they want to distribute their folders.
Just thinking out loud...
PS. GO PACIFIC!
