Where is leaderboard documentation?

Hi

I am unable to find any documentation for leaderboards in Telligent 10, other than this: https://www.telligent.com/community-platform/features/leaderboards/

The two things I am trying to find out are: a) where do I scope the leaderboards to specific activities? (I want a leaderboard to be based on the number of times people in a role have replied to questions in forums, and how many times they have had an answer verified as THE answer). b) an explanation of how leaderboards are otherwise calculated. 

Oh, and another thing. I want to test the leaderboards, because they didn't work at all in 2008. But I see that by default the job is scheduled to run at 2.45am. Is that because it is a huge job requiring a lot of resource, regardless of the number of leaderboards or members it has to check? Or could I get away with setting it to 'every few minutes' just while I have only one leaderboard with 10 people in it, to see how it works?

Thanks
