One weakness of the Fenwick stat is that teams tend to go into a defensive shell when leading and thus get outshot (and obviously, the opposite happens when they are behind). If a team is behind often, the regular Fenwick would tend to overrate it and would tend to underrate teams that are usually leading. The "Score Adjusted Fenwick" stat attempts to account for that by giving more weight to shot differential when teams are tied and less to shot differential when the team is ahead or behind - hence "score adjusted." This statistic, over the long term, has a high rate of success in predicting how teams will do over the course of 82 games.
