Game Tracker: A team's momentum, or heightened tempo state, is measured by using shots on goal per second as a proxy.

If a team takes more shots than a team would on average over the last 5 minutes of play, their Game Tracker meter goes UP, and if they've taken fewer shots than the average for the period their meter goes DOWN.

For example, if the average number of shots per period is 10, that's one shot on goal every two minutes of play. Therefore, if a team takes more than a single shot within that two minute average, the meter increases. The more they shoot in bunches (like on a powerplay), the faster and steeper their momentum meter will rise.

On the flip side, if they take no shots, their curve drops accordingly.

Game Dominance: Game Dominance is simply the difference between two competing team's Game Tracker meter values at any point of the game. Whereas the Game Tracker measures each team's play compared to the average team on a period by period basis, Game Dominance measures their play relative to each other.

Game Dominance = (Team1 Game Tracker meter) - (Team2 Game Tracker meter) calculated in real-time throughout the game.

The DOM% is calculated by summing the amount of difference and the length of time that a team's Momentum is higher than the other teams (i.e. area under the curve for the calculus lovers out there).

For every NHL game, the DOM% is graphed in real-time and recorded for each given period, as well as for the game overall.

The DOM% tells how much of the play (i.e. momentum) was controlled, or dominated, by either team.

The DOM% of both teams will always add to 100%.

MVP: 'Most Valuable Player' (MVP) measures not surprisingly the MOST VALUABLE PLAYER by calculating the amount of EXTRA Point Shares the player has earned compared to a replacement player (e.g., an AHL junior call-up) at his position, and then converted to a percentage of his team's total points in the standings (taking out the loser points first).

In simple terms, MVP tells us how what % better that player make his team in the Standings for his role and position.

How the NHL Trade Maker Works

Two NHL teams only - 4 players maximum per team.

For both teams, it calculates the overall team gain or decrease in the following eight categories:
Change in team Goals (%)
Change in team Assists (%)
Change in team Shots (%)
Change in team Blocked Shots (%)
Change in team Hits (%)
Change in team Giveaways (%)
Change in team Takeaways (%)
Change in Salary Cap spent ($)

Step #1: For each traded NHL player, it calculates the impact of him leaving his current team, as well as the impact he'll have on his new team, in the eight categories above.

Step #2: Adds up all the individual players' net impacts to each team (calculated in Step #1) to estimate the total overall % change to both teams after the trade.

Assumptions

Players available for trading have to have played at least one NHL game this season.
Players will continue to perform at the same production rate the rest of this season regardless of the number of games they’ve played season-to-date.
Players traded will get the exact same ice time per game with their new team.
A player is compared to the average of at least two players on his new team that get similar ice time per game.
NHL Player stats used are for the 2011-12 season-to-date only.
Wingers are grouped together and not separated by left and right wing.

Interpreting results

On occasion a traded NHL player will receive ice time on his new team at the expense of currently more productive players, resulting in a negative impact to his new team. Goaltenders that are traded will have an impact on the Salary Cap category only.
