Forecasting based on 6 computed probability points

[yasould]

Hi all,

Upfront i have not got a clue of Mathematics.
I have computed probable endscores of soccer match based on the following forms (total form = form for the whole season, form12= form of the last 12 games, form10= form of the last 10 games...last 4 games) see the table in the attached excelfile

Based on the form of both teams for the whole season the game should end up in 1-1
Based on the form of both teams for the last 12 games the game should end up in 1-0
Based on the form of both teams for the last 10 games the game should end up in 0-0
Based on the form of both teams for the last 8 games the game should end up in 1-1
Based on the form of both teams for the last 6 games the game should end up in 0-1
Based on the form of both teams for the last 4 games the game should end up in 0-0
Forecast endscore is looked for

Thanks in advance for any constructive support on that.
