Each player has a "personal" stage of an area, the highest online player's difficulty stage in an area will be the "effective" difficulty stage of that area.
Each player has a 6-element long list in their data. Each element in the list has a chunk position and time value. Every tick the player will first, find the stage element its current position is in, and increase the time value of that stage element. If the time value when increased is over 24,000 ticks the next stage element will have its chunk set to the players current position, have its time value reset, the old stage element will have the next stage element's old chunk, and have its time value reset. To determine if a player is in a stage element, it checks if the player is within 16 chunks of the stage element's chunk, it starts searching at the last element, ending at the first. The "effective" stage element of a chunk can be found by searching every **online** player for their stage element for the chunk and then picking the highest value.
