Where are the breakdown of points people recieve?

I see my measly 10 points I received in june 2013 that I had to ask for.

But I cannot see the breakdown of points received by the lifetime members. Why can I see a breakdown of pts I received from one staff member, but I cannot see the breakdown of all the other members and how they got them ? Why does this need to be a secret. Or maybe is not a secret I just don't know where to look. There should no reason for it to be a secret. It is a point system and we should see how people get their points. So we can copy what they do.
