> We're doing two things wrong in CI.  First, load can change between calls, which can
cause a negative severity even though it meant to subtract whatever it added before.  Second,
we should report based on how much IO we're using, since a 1T throttled to 5MB/s is less impactful
than a 100MB running at full speed.
