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

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
