This is pretty much what analog's cache file does. It stores the total
number of hits for each item, but doesn't cross-reference (say) files and
referrers.

The only issue is when the historical cache file overlaps the last seven
days. Does that answer your question?

Anywhere you want.

I guess you've got two main choices. The one I recommend in the docs is to
create a cache file from each logfile: then when you want a report, analyse
all the cache files. The other would be to create a cumulative cache file
each week based on the last cache file and the new week's logfile.
Personally I think this second procedure is much more likely to get
confused, and when it does, all the data is corrupted together. :)

Not at all. I wish all the questions here were this intelligent. :)
