I was checking out each team's average PPD (meaning the average PPD of active users) and Team Rage3D does pretty well with over 300k. Most teams are 180k or less.
Except nVidia. They've employed their AI learning machine and it's kicking serious ass @ 500M PPD. 2nd place is raplab - also part of the NVIDIA team at 400M PPD. Basically NVIDIA earns about 10% of all the points awarded.
Their WU return ratio is way down - about 10 - 20k per day between the two "users" or roughly 0.7% of all WUs.
