PENGIRAAN RATING BAGI KELAB BOLA SEPAK (BERDASARKAN ELO CALCULATION)

Kiraan rating bolasepak

R_n = R_o + K*G (W – W_e)

Or

Points Change:

P = K*G(W-W_e)

Where;

R_n =  new team rating

R_o = old team rating

K = weight index regarding the tournament of the match

G = number from the index of goal differences

W=result of the match

W_e = expected result

K value (AFC)

Final = K40

Semi final = K30

Quarter final = K20

 Group,Round 16 n Round 32 = K10

Preliminary matches = K10

Leagues(Malaysian) = K5

G value

If the game draw or is won by one goal : G = 1

If the game is won by two goal : G = 1.5 @ 3/2

If the game is won by three goal or more goals : G = (11+N)/8

W value

W is the result of the game:

1 = Win

0.5 = Draw

0 = Loss

W_e value

W_e = 1 /  (10^(-dr /400) + 1)

Dr = differences in rating + 100 for a team playing at home, so dr of 0 gives 0.5, of 120 gives 0.666 to the higher ranked team and 0.334 to the lower, and of 800 gives 0.99 to the higher ranked team and 0.01 to the lower
