If you've figured out all of your business requirements and really want to report on page views per tracking code, keep in mind that tracking codes are basically eVars, so they persist beyond the initial hit where they're set. By default, tracking code values persist for up to a week (7 days) after they had been set.
Example:
Day 1: User opens Page A with tracking code "abc123". User then opens Page B. User then leaves the website.
Day 5: User then opens Page C. User then leaves the website.
Let's say your website only ever had that 1 user who viewed those 3 pages. And let's assume that your tracking code has the default "Week" expiration. Then when you run your report for Day 1-30, tracking code "abc123" will be reported with 3 page views: 2 from Day 1, and 1 from Day 5.
So, make sure you know what you're reporting.
