About the pointsystem
A good Ranking needs a good and fair Point System to rank and classify the
What is the ranking system?
Based on the Pointsystem, the Players are sorted descending after Points,
Players with more Points are on top and Players with less Points are underneath.
Who is ranked in the Ranking ?
All Players who have at least played ONE game ! It is not that easy to defeat Human Players ! Startplayers (700-1000) are classified than Beginners, exp. Players (1000-1500/2000) than Veteran, good players (1500/2000-2000/3000) than Elite and perfect Players than Master (2000/3000-3000/4000). Values are dependly from the amount of activ players.
Which ranks can be achieved ?
Beginners: just play
Veteran: > achieve easy more than 1000 points
Elite: Tourneywinners and setted from Council or achieving points
Master: Leaguewinners and setted from Coucil or achieving points
A Player starts the Ranking with 1000 Points and is listed in the Ranking when he has played at least ONE match. Players without at least ONE played Game will be listed but unranked ! Start Players get no Minuspoints
Elo-number == Rankingpoints
Every Players get an ELO Value, when players has no points in Ranking (because not playing) he get his first Number 700 Points. Seeing Starting Conditions
This number will be multiplicated at last. More K-Number means more points, or more minuspoints. That are the Dependies:
less than 30 games: 50
less than 2400 (1750) Points: 30
when not: 20
Difference are computed from own Elo-number with other Elo-number
Player1 = 1800 Ranking Points. Player2 = 2400 Ranking Points
Difference1 for Player1 1800 - 2400 = -600
Difference2 for Player2 2400 - 188 = 600
This number represent your result in Game, 1 stands for win, 0 for losts
when tied = 1 * (amount teams - RankinGame) / (amount teams - 1)
Win = 1
Losts = 0
Player 1 beat Players2, Player3
Player1 = 1 (win)
Player2 = 1 *(3-2) / (3 - 1)= 0,5 (tied)
Player3 = 0 (lost)
The Expectation will be computed per Formulare from Professor Elo. This number represent your
Probability in Game, better players have a greater Expectation to win.
Expectationnumber = 0,5 + 1,4217 x 0,001 x Difference number
- 2,4336 x 0,0000001 x Difference number x Abs Difference number
- 2,514 x 0,000000001 x Difference number x (Abs Difference number)*2
+ 1,9910 x 0,000000000001 x Difference number x (Abs Difference number)*3
Player1 = 0,5 + 1,4217 x 0,001 x (-600) ==> -0,35302
- 2,4336 x 0,0000001 x (-600) x (600) ==> -0,0876096
- 2,514 x 0,000000001 x (-600) x (600)*2 ==> -0,543024
+ 1,9910 x 0,000000000001 x -600 x (600)*3 ==> -0,2580336
Player2 = 0,5 + 1,4217 x 0,001 x (600) ==> 1,35302
- 2,4336 x 0,0000001 x (600) x (600) ==> 0,0876096
- 2,514 x 0,000000001 x (600) x (600)*2 ==> 0,543024
+ 1,9910 x 0,000000000001 x 600 x (600)*3 ==> 0,2580336
The Change is the real result of the player, dependly from Expaction. Multiplikated from the
Change = ( Result - Expectation ) x K
Player1 = (1 - 0,01958) x 30 (under 2400) = 29,4126
Player2 = (0-0,98042) x 20 (normal) = -19,6084
Surpluses / subtraction
Players who are bader in gamerank will be added, players who was better will be subtracted.
So can players win more points, when more opponents are in. But too more loosing points.
Change ->PlayerA PlayerB PlayerC
Player A 30 20 = 50 for Player A
Player B -30 15 = -15 for Player B
Player C -15 -20 = -35 for Player C
Result: That makes 50 Rankingpoints for Player A. B and C will lost points.
