How do you find these figures?
To sum it up, the centerpiece is the Merit file which is public and updated every Friday . It can be found at here:
https://bitcointalk.org/merit.txt.xz. The file is limited to the last 120 days of data, so all previous records come from my cumulative set of such files.
Any other information not present in the file will need to be pulled down from the Bitcointalk website itself by scrapping data from user profiles and user posts.
Lastly, apply a bit of gray matter to give different information views derived from the raw data obtained. The Dashboard sums it all up and gives us filtering capabilities.
The figures referenced in my previous post on this thread come from the Global Summary tab, by comparing data shown there for the most recent complete weeks.
Thats about it...
