I initially overlooked the less than sign in your example. With
the less than sign, it now makes sense to me. It would work, for
example, a machine that takes 10 minutes to do binutils, we are
saying that a < 0.1 SBU package would take under a minute.

That would probably work, as SBU's are bit of a stretch to pinpoint
accurately. Too many unknowns. It's not just CPU speed, but the
speed of the disk, amount of RAM and other variables we can't
account for.
