well, gentoo really is a *insertbadwordhere* when you install it the first time. You have to built everything from scratch, deciding what you want. So you do only have what you need, no support in the programs for nonsense things.
Who needs a program, which got the gnome-gui routines in it, when you use kde. Also, who needs programs compatible with any 64-bit-cpu, when it could use especially the routines for your cpus.
Thats what gentoo is about. Choises.

If you wanna try out gentoo, i would be really happy to help.
But, back to topic: these scores really rock. i mean really really.
