USAR: National Ranking System

The new USAR Rankings use a "double-jump ranking system". (Click here to download the MS-Word version of the complete explanation of double jump ranking with graphics)

The double-jump ranking system is dynamic in its ability to move players as it responds to results based on the level of the player beaten and the time and ability level of previously recorded wins of this winner.

  • The system is dynamic, letting players move up the rankings quickly. All matches are computed in the order that they were actually played regardless of when they are actually submitted for ranking. Also player movement is calculated and occurs after each and every match. (The player's movement is not calculated by using a group of match entries with calculations based on the starting position of each player for that ranking run.) This ensures that each player's ranking reflects their actual track record and their increase or decrease in ability level over time.
  • The system disregards wins that would be considered "anomalies" (flukes) by enforcing time constraints on "the next win" against the same opponent.
  • The system allows players to move up in ranking immediately following a win against a player of a lesser ranking than their own previously recorded "best win". This movement or non movement is also dependent on the time since that previous win.
  • The system does not unjustly penalize the losing player by reducing their ranking to a level below that of other players who have not yet proven their ability to defeat said losing player.
Note:HWL = High Win Last ie: best win to date within time constraint

 Assume starting point for all scenarios
              A = 100  A's HWL = 100 to start B = 60 C = 70 D= 50
-------------------------------------------------------------------------------------
 Scenario 1:
 
   A defeats B ------> A = 100 HWL= 60 B=60
   
   A defeats B --------> A = 60 HWL = 60 B = 61
   
-------------------------------------------------------------------------------------
 Scenario 2

   A defeats B ------> A = 100 HWL= 60 B=60 

   B defeats A --------> A = 100 HWL = 100 B = 60

-------------------------------------------------------------------------------------
 Scenario 3 
   A defeats B ------> A = 100 HWL= 60 B=60 C = 70 D =50 HWL is updated above C

   A defeats D ------> A = 60 HWL= 50 B=61 C = 71 D =50 A moves  above B

-------------------------------------------------------------------------------------

 Scenario 4
   A defeats B ------> A = 100 HWL= 60 B=60 C = 70 D =50 HWL is updated 

   A defeats C ------> A = 70 HWL= 60 B=60 C = 71 D =50 A moves above C 

   A defeats D ------> A = 60 HWL= 50 B=61 C = 71 D =50 A moves above B

   D defeats A ------> A = 60 HWL = 60 B=61 C = 71 D =50 A's HWL reset to self ranking
