чёт типа символических игр, побед, которых не хватает до лидера. приплюсуй ГБ каждой команды к количеству побед этой команды - получишь количество побед лидера
edit: нарыл в вики "In sports, the phrase games behind or games back (often abbreviated GB), is a common way to reflect the gap between a leading team (said to be that many games ahead or GA) and another team in a sports league, conference, or division. It is determined by adding the absolute difference in wins between a leading team and the team of interest to the absolute difference in losses between the two teams, and dividing by two. The leading team itself is always zero games behind. Usually this is indicated in tables by a dash rather than a zero."
