Most efficient system for one player to achieve a rating of zero.
What is the minimum number of players required to help one player achieve the rating of zero?
Minimum number of players to get to 0, given initial players all have 1200 (setting aside provisional status for the moment).
A pair of players with equal rating can theoretically work to get one player's rating down by 360 points (720 difference no longer changes ratings).
So you need one pair of players to get down to 840, two pairs to get to 480, four pairs to get to 120, and one 600 rating player to get to 0. To get the 600 player, you need a pair of 960 players, and thus about four 1200 players. So, you need at minimum 12 players to cooperate for one to reach zero.
I suspect that starting with provisional status would accelerate this process, as you could lose rating points in larger chunks. This is obviously not the most efficient way to reach zero.
