The long long long term trend of St. Louis Blues shooting and save percentage

The trend lines below show the shooting and save percentages and the PDO for the Blues as of each game played since the start of the 2005-2006 season.  For instance, by the end of the first game of the 2007-2008 season the Blues had encountered a total of 3012 shots against and 308 goals against since the beginning of the 2005-2006 season.  This is a 89.77% save percentage during that time period.  Because of the wild variance in the first few games of the 2005-06 season (due to the formula I am using to calculate this trend) I hid the 2005-06 season so the lines would remain readable.  You should also notice that the axis for trend charts do not start at zero.  Use the reference lines as your guide for any comparative analysis between teams.

This isn't any type of serious analysis, but something fun to play with on a Friday afternoon.  I do find it interesting, however, that over the past couple of seasons the Blues save percentage has improved while the shooting percentage of the team is still somewhat stagnant when compared to the rest of the league during the same time period.
