directory critic point system ?? anyone knows

I am trying to find out how actually directorycritic.com assign list positions to each directories

caz in the list my directory says 0 points though when i click details it says Total Points: 29

and in the list the directory just above me shows this

though my directory shows

so why am i still under that directory ?? in terms of listing positions ??
can any one explain this if u know how it works

 

Maybe it's just temporary ranking, just wait some time and check it again.

 

ya may be they update list manually or on weekly basis etc

 

its hard to know the point system

 

This is the very hard
