Major League Soccer Standings Misleading

I was looking through the sports section of today's Gainesville Sun when my eyes fell upon the Major League Soccer standings.  I saw that "my" Orlando City Iron Lions were a bit down among the teams in the East with a 2-4-2 record (with MLS, the numbers represent wins-losses-draws, while with other leagues the order is wins-draws-ties).  Down at the bottom of the division were two teams: the Philadelphia Union and the Montreal Impact.  Philly had a 1-6-3 record while the basement-dwelling Canadian team was 0-2-2.  I had to do a double take when I saw this, for this meant that one team had already played 10 games while the other had only 4. I already knew that the Impact were deeply involved in the CONCACAF (Americas) tournament involving league teams in the Western Hemisphere and had made it to the championship round.  No doubt some of its MLS regular season games had been rescheduled to make room for its tournament games...the same happens for the European leagues as well with their various extra-league tournaments.  But that still doesn't account for the wide disparity in games played.  Of course, eventually all of the MLS teams will finish the regular season having played the same number of games.  But since, on any given day, standings are computed based on 3 points per win, 1 per draw and 0 per loss, a team with fewer games played will tend to be down in the standings while one that has more games under their belt than others will have a more favorable position. Although this may present an illusory impression about the respective teams' successes, mid-season coach firings and player trades may result, based on popular reaction to the different teams' positions.  So I'm a little bit disconcerted that the various teams have such a wide range in games played, but perhaps this is unavoidable given various circumstances (including the aforementioned tourney).  Still, regarding the ongoing standings, they instead could go by an indexing system whereby the total accumulated points, divided by total games played, would determine the relative positions of the teams.  In the end it would amount to the same thing when all teams have played the same number of games, but during the course of the regular season it would give a much more accurate indication of how well or bad different teams are doing...
