most installs involve multiple files.

you equations is correct if all the downloads are done, and then all the decompression is done.

as downloading and decompressing require different resources (bandwidth, cpu), these could be effectivly parallelized. after a package is downloaded (or read from cd) it joins a decompression queue. even more time saving :-)
