# Data notes

> What the numbers mean and their limits: time zone, perspectives, reloads, freshness, history, attribution and email opens.

1. **Days are America/Chicago.** A listing viewed at 11 pm Pacific counts on the next Chicago day.
2. **Two perspectives.** Listing numbers count every Ruuster site, because you own the listing. Lead
   and summary numbers count activity on your sites, because you own the audience. They aren't meant
   to add up to each other.
3. **Views count reloads.** Use `views.public.users` (roughly distinct browsers) and
   `views.loggedIn.uniqueLeads` to estimate people. Both are distinct per day; over a week or a month they
   are the sum of the daily counts, so a returning visitor counts once per day they came.
4. **Freshness.** Yesterday's numbers are usually complete by mid-morning Central, and today's are
   refreshed through the day. Use `meta.coverage`, not the clock, to decide what's final. Google
   Analytics can revise the last 48 hours, and email opens and clicks keep arriving for about two
   weeks, so re-pull the last few days on each sync.
5. **History.** Google Analytics history goes back to `coverage.ga.from` in `/me`. Ruuster's own
   activity history begins about 90 days before your brokerage was enabled and grows from there. Ask
   your CSM if you need more.
6. **Attribution.** A listing missing from `/properties` usually means the listing agent's MLS id isn't
   on their Ruuster profile. `attribution` in `/me` shows how many of your agents have one. Ask your
   CSM to add the missing ids; listings typically appear within a day. Listings from your MLS office
   are included only after Ruuster confirms the office is yours.
7. **Lead identity.** A visitor becomes a lead when Ruuster can tie them to a contact. Activity from
   before that stays anonymous.
8. **Tour requests** on a listing and tour requests in a lead's activity are measured at different
   points, so the two can differ slightly.
9. **Email opens.** Human-open figures leave out opens that look automated. Mail scanners change often,
   so treat open rates as indicative.
10. **Contact details** in responses carry the same obligations as your CRM data.
11. **Where data is processed.** API data is stored and processed in the United States, including data
    about Canadian brokerages and their leads.
