They already do that with things like 'turbo mode' - under any
system that calculates work as the product of a static performance
measure and job time, anything you do that increases the actual
performance and so reduces the job time decreases the amount of
work you're accounted as doing.
There are always likely to be perverse incentives as long as we
insist on accounting using artificial metrics rather than actual
things we care about (e.g. amount of analysis jobs actually done).
Clearly we need some sort of approximation for the VOs that don't
have a central job supervisor like Panda, but I assume there's also
a reason that we need to this even for the VOs that do, like ATLAS
and LHCb.
