That remains to be seen yet. Our test is still under way. If all SBUs are
rather similar then taking a average wouldn't be a bad thing just to get
one number in the book. If not, we'll have to rethink this. Perhaps go back
to simple classes that were suggested before like Class A taking very long
(glibc/gcc) to Class D/E which takes practically no time at all (kernel, gzip)

Then we have to ask what do we use for a carefully crafted build situation.
Practically it's easier for an LFS book editor to use his times in such
case since when a package is added to the book, SBUs can then be updated
immediately.  Also it's no rocket science. Coming up or building a
special computer just so SBUs would work out is overkill.

Sure go for it. It'll give us a better idea how SBUs work practically.
