in the x86 Quick Install Guide  it is stated under "Code
Listing 2.38: Last edit of make.conf":
You might want to recompile your whole system twice to make full use of
your latest configuration changes. It would take quite a long time to
complete and yield minimal speed benefits. It is recommended that you
let your system optimise itself gradually over time when new versions of
packages are released.
--end of snip--
1.) The phrase "recompile your whole system twice" implicates (at least
for me) "emerge -e system && emerge -e system", while I read on the dev
list about the stage1-discussion , that it is recommend to do "emerge
-e world && emerge -e world && emerge --depclean", when you change your
compile options (well yes, and USE flags).
2.) In chapter "5.e. Configuring the Compile Options"  of the
Handbook there is nothing written comparing to this.
In the next Code Listing "Code Listing 2.39: Update your packages" of
the x86 Quick Install Guide there are some recommendations, what you
should, when you update your system:
--end of snip--
Again you can find nothing about these recommendations in the handbook
in chapter "1.c. Maintaining Software" . On the other hand you find
there the advise to run "emerge --depclean" and revdep-rebuild" after an
update of your complete system.
Any thoughts about this?
I think, both (handbook and guide) should be made consistent with each
other, with the handbook including some more informations about why you
should do this and that.
