Alright. Updated with Grav's example taken from BCube's idea of weighted judging. Also updated the Activity to 35%, since that is the minimum % for Staff members, and hence should be good enough for this.
Now, do we not agree that 4 months is an ample amount of time? If we really wanted, we could just as easily incorporate the system WW implemented for Senior Members, and use that as the required mimimum.
