The WP for 1.4 wins and 1.3 losses.
And the reason total games is important ... if you are a team that has a WP over .5000 (striving for postseason play), it is more advantageous (for example) to win a game at home and lose on the road (if you are to win one and lose one) vs. the converse. IOW, having 0.7 wins and 0.7 losses is better than 1.3 wins and 1.3 losses.
