Knowledge is king and when it comes to wagering. The more you know, the better the chances you will consistently be able to formulate winning betting strategies. Whether you like it or not, analytics are a crucial part of ensuring your bets are successful. If you dig a little deeper into the numbers, it can help you to be a more successful bettor. And that’s where the Adjusted Efficiency Margin comes into play, an easy stat to calculate, yet one that can make all the difference.

The adjusted efficiency margin was started by metrics king Bill James in baseball and has since been applied to several other sports, including hockey. In simple terms, the adjusted efficiency margin – also know in hockey circles as the scoring efficiency ratio- is comparing a team’s offensive prowess against their defensive stubborness. It shows the number of goals a team would be expected to outscore the average opponent by without taking into consideration the location of the game.

Through the end of February, the Washington Capitals were the NHL’s best in this category. The Capitals had scored 207 goals and allowed 129 goals, giving them a scoring efficiency ratio of 1.60.

### How To Use Adjusted Efficiency Margin

How does the adjusted efficiency margin, or scoring efficiency ratio, work? Glad you asked. The scoring efficiency ratio compares a team’s goals scored against its goals allowed to give an indication of the number of goals a team scores for every goal it gives up.

This single number highlights both the teams offensive ability and its defensive ability, and the higher this number is, the better it is for that team.

It also seems to be a stat that you can count on in the long run. Last season, the Stanley Cup champion Pittsburgh Peguins owned the NHL’s second-best scoring efficiency rating at 1.21. The San Jose Sharks, who lost in the final to the Penguins, were sixth-best at 1.14.

#### How To Calculate Scoring Efficiency Ratio

Unlike many of hockey’s so-called fancy stats, which can appear to be as complicated to figure out as Egyptian hieroglpyhs, tabulating the scoring efficiency ratio for an NHL team is as easy as adding up how long a two-minute minor penalty will be.

You simply take a team’s total goals for and divide it by their goals against. It is the margin of goals that said team should be winning games by onnaverage.

When wagering, you’ll want to put your money on the teams with the higher scoring efficiency ratio, especially when they are playing a team with a negative ratio.

#### Scoring Efficiency Ratio And The Stanley Cup

Teams that rate among the top in scoring efficiency ratio are the teams you should be backing to win the Stanley Cup. The numbers don’t lie.

In 2015-16, the Pittsburgh Penguins had the second best scoring efficiency ratio (1.21) in the NHL during the regular season. In 2014-15, the Eastern Conference champion Tampa Bay Lighting (1.26) were second overall and the Stanley Cup champion Chicago Blackhawks (1.18) were fifth in scoring efficiency ratio.

Since 2009-10, every Stanley Cup champion has finished in the top nine in the NHL in scoring efficiency ratio. Let’s face it, the name of the game is to score more goals than the other team. That’s why you always put a lot of stock in this stat when analyzing your Stanley Cup choices.

Avoid teams with negative scoring efficiency ratios like the plague. Backing them to win the Stanley Cup is fool’s gold, and you know what they say about a fool and his money being easily parted.

How much weight should you give to teams that are strong on the power play when making a wager on an NHL game? As it turns out, not that much.

While the San Jose Sharks, last season’s Stanley Cup finalists, led the NHL in power play goals with 62, the 2015-16 Stanley Cup champion Pittsburgh Penguins ended up 12th overall with 48. The 2014-15 Stanley Cup champion Chicago Blackhawks were 15th overall in power play goals (46).

The power play is the icing on the cake. It’s an uncontrollable variable – you don’t klnow how many penalties will be called in a given game and generally, the deeper you get into the playoffs, or into a playoff game for that matter, the fewer infractions that will be whistled.
