Football forecast: 15 home and Away algorithm-program is still debugging

The algorithm from my original, reproduced please indicate the source.

The algorithm premise: "Home advantage effect" that the team in the home game to win the odds are higher than the win rate in the away game. Home advantage

The most obvious sport is the non-football, in the three major European leagues in the Premier League, La Liga and Serie A, the home team has a winning ratio of 65%. In the other 24
Of the country's 40 soccer leagues, the home team has a winning ratio of 63%.

Algorithm:

W = "Home team last 15 game points value" *100/60-"away the last 15 game points value" *100/40

can also be directly simplified to W = "Home team last 15 game points value" *1.7-"away the last 15 game points value" *2.5

Conclusion:

When W>10 Master wins

When the 10=>w>=0 master wins the flat

When 0>w>=-10 the main flat

When the W<-10 main negative
