I'm not sure which (version of which) man page you found this info on,
but when I originally started using smartmontools years ago I set up
that same daily-and-weekly cycle, and I think I did so based on these
two smartmontools-support list threads:

  http://sourceforge.net/p/smartmontools/mailman/message/7331341/
  http://article.gmane.org/gmane.linux.utilities.smartmontools/1443
    Subject: Recommended test and frequency


  http://sourceforge.net/p/smartmontools/mailman/message/7331590/
  http://article.gmane.org/gmane.linux.utilities.smartmontools/1627 
    Subject: Testing Interval


In short, there's no absolute "correct" answer, but this daily/weekly
schedule is a compromise between catching failing drives fairly quickly
and causing undue stress on the drives, and is seems to be appropriate
for most environments.

I haven't been following the issue particularly closely since then, but
I haven't had any reason to change away from that schedule on my
servers....
