You will want to use a separate table not the user table since this
will be scratch data. If you want to display split values for users
and guests assign everyone an ID from the new table and place that in
a cookie var. By using a cookie you can see if a visitor has been to
the site, even if they closed their browser and came back. When a
guest logins in update the table to record assigned to the ID reflect
a user instead of a guest. You can then get counts for each type.
You'll also want to dump old data from the table periodically.
I think 10 minutes is too short. What kind of site is this? I'd think
20 to 30 minutes would be better, especially if you have any reading
material.
Sincerely,
Mike
