I developed Special Teams Efficiency (STE) as a way of comparing the gains and losses in special teams efficiency between teams.  It's a measure of efficiency (% of power plays converted + % of penalties killed) and nothing else.  Penalties drawn or taken don't figure into it directly.  I explained then:

If we had a simple metric to apply to special teams, we could get a sense of just how much of an impact special teams can have on a season.  Since the league average for power play success percentage plus penalty kill success percentage is 100, why not add the two and use it as a baseline for measuring special teams efficiency?  Though the tendency to regress toward the mean may be somewhat less strong (but then again, maybe not!), it may still be useful as an evaluation tool.  In this case, we'll call the combined number Special Teams Efficiency, or STE. Since the post-lockout orgy of power plays (2005-2007) the per team yearly average of special teams situations is 643.  If all teams were to draw the same amount of penalties, a team with a 100 STE would net zero special teams goals. It follows, then, that a team with a 105 STE would net 32 special teams goals more than average, and a team with a 95 STE would net 32 special teams goals less than average .

STE correlates with season-to-season performance much more strongly than I'd initially anticipated.  Below is a table containing the R^2 Correlation between team STE and total points:

Year R^2 Points
2005-06 0.47
2006-07 0.44
2007-08 0.36
2008-09 0.41
2009-10 0.33
2010-11 0.47
2011-12 0.29

Though the season is still too young to gain anything from goals gained/lost, there are some interesting numbers at play.
