lol.
Heres the more detailed explaination
The dark green pips are followed by light green pips, which are then followed by 'golden' pips. When the limit these can display is reached, the display is prefixed by a golden Star, and started again. If your reputation is zero then the neutral grey pip is displayed. Negative reputations are displayed in a similar manner using light and dark red pips and stars.
Each time you 'lap' the limit of the pips display, another star is added. The number of stars in unlimited.
