I run Rosetta@home, NumberFields@home and malariacontrol.net as CPU projects, and among floating-point intensive projects, malariacontrol.net gives by far the lowest RAC, even with an identical distribution of resources.
Why is this? Is it just that malariacontrol.net involves the least amount of integer math, and hence gives the least credit?

Not really. Credit ratings were once based on the idea of working out how many floating point computations are done, but for many projects (including the malariacontrol.net simulator) this isn't feasible, and credits are granted based mostly on how long work-units take, with some arbitrary scale factor (see http://boinc.berkeley.edu/trac/wiki/CreditNew).
Think of it as just an indicator of how much computing power you've donated to :-)
