You said it : *should* ! Now, imagine you have N real servers, exact
same machines, serving the same content. And for any reason, the CPU
load on one of them skyrockets. Do you still think it *should* receives
as many requests as the other RS ? Personaly, I don't. Decreasing its
weight will give it an opportunity to come down.
You could also have more complicated setups where a few RS are serving
differents contents. A real server becoming loaded because it's part of
a loaded virtual server should not impact the global load of another
unload virtual server.

That's actually the way I initially do (when lvs/piranha starts). Then,
the weights may vary a bit due to CPU load, but globally keeping the
initial ratio between RS.
