Home and away records are significant factors in predicting sports betting outcomes because teams often perform differently depending on the venue. When analyzing head-to-head trends, you should look at how teams have performed at home versus away in recent years. This can give you insights into the likelihood of a team winning or how often games between the two teams go over or under the total points line. By considering who's at home and who's away, along with the recent matchups, you can better estimate the probability of various outcomes and make more informed betting decisions.
