It is currently set to refresh every stats every hour.
The history snapshots are taken at midnight (london time).
It's going to display day by day for the past 30 days. Then I will make a month-by-month, that will probably be good until we need year-by-year.
You are so awesomely helpful and talented, again I thank you.
As your website is not primarily income based / supported if the hourly refresh causes bandwidth or other costs. Maybe just the daily refresh and a mention to people to manually refresh as they need during the day.
Regardless love your website; it is so helpful, it has taught me a lot. Cannot await your next app...
