Hello geostd,
My guess (no more than that) is that we are conserving the last of the HPF units to make them last until FightAIDS@Home is boarded for BOINC. So most (not all) randomly assigned work units are for FAAH.

The statistics list computer hours, points and results. There is no official way to convert that into teraflops. So people do their own calculations, using whatever reference processor seems reasonable to them.

The grid system assigns work units at random from those inserted into the grid system, if the machine qualifies for the project and does not have opt-out settings which force one or the other project. For some period after launch of the new project, we have a higher proportion of FightAIDS@home work units to help with the press coverage. When new users hear about the FightAIDS@home project and WorldCommunityGrid for the first time, they can be surprised and confused by a Human Proteome Folding work unit. So we will gradually establish a more normal equilibrium over the next few weeks.
