Intervals
The season is divided into equal sized intervals, according to the days in the season, with a game in each interval weighted the same. The weights used in each interval are provided by you.
Home/away weighting
The weight of the game for the home/away/(or both if it's a neutral site) team is multiplied by the home/away/neutral weighting. If you think performance in home/away/neutral games is more indicative of a teams performance, make this weight larger.
