After an icy Week Seven, only one team remains undefeated: the AFC's Negligent Discharges. Meanwhile, previously winless teams Whackers and Orangebloods finally put a 1 in the win column. Here are your standings and Week Seven OPR rankings.

And here are the Week Seven OPR rankings. To recap, OPR stands for OIL Power Rating. It is based on the power rating created by the Oberon Mt. Fantasy Football League, which has been featured on ESPN's Fantasy Focus podcast and is used by many leagues across the country. From their website:  
The Formula

The Oberon Mt. Power Rating Formula attempts to give commissioners and owners alike a tool to predict a fantasy team's potential performance by not only looking at their average score, but also factoring in intangibles such as an owner's managerial skills (using winning percentage) and luck (good teams losing to the hot team of the week and poor teams beating better teams having a down week). 

Oberon Mt. Power Rating Formula

The Oberon Mt. Power Rating Formula combines Average Score (60%), Highest Score plus Lowest Score (20%), and Winning Percentage. (20%) to come up with a team's Power Rating for use in comparing teams both in the same league in ways other than just by Win-Loss Record. The Oberon Mt. Power Rating Formula is sure to provoke endless hours of trash-talkin' and one-upsmanship!

The OIL's adjusted power rating takes everything measured by the Oberon Mt. Power Rating Formula and then calculates how each team compares to the rest of the league for that season. So, what is measured is not raw data that fluctuates by season but, instead, how much better or worse a team is than the average team for that season. But first, the baseline raw power rating needs to be calculated.

The Oberon Mt. Power Rating Formula is best explained by its creator: 
(avg score x 6) + [(high score + low score) x 2] +[ (winning % x 200) x 2]
​10
In English:
​
#1. Multiply the team's average score by six. Average score is the very basic stat to judge a team's prowess.

#2. Add the team's highest score to their lowest score (Deviation), and multiply the result by two. Over and above the average score, the Deviation gives more importance to a team's highest scoring game, while also punishing a team a little more for their lowest score.

#3. Take the owner's winning percentage and multiply by 200, then multiply that by two. This portion of the Formula more than anything rewards and punishes for all the little intangibles associated with coaching a fantasy team. For instance, an owner that continues to win despite a less-than-impressive lineup is rewarded over and above their lagging average score. On the other hand, an owner that loses because he starts players on their bye week, or leaves injured players in their lineup, suffers twice . . . from points not scored by missing players and for the resulting losses.

#4. divide the total by 10.

The result is the Power Rating . . . or, if you like, the Potential Rating, since it actually is meant to judge the potential score a team might be expected to score on any given weekend compared to its average score. Remember, as the season progresses, a team's average score changes more and more slowly as the number of games included increases. The Power Rating formula takes not only the average score into account, but also recent extreme high or low scores, and winning or losing trends. Obviously, you will need a few weeks of data before a viable PR can be arrived at. We don't start reporting Power Ratings until after Week 3 games.

Definition of Terms:

Average score - Total of a team's points scored divided by the number of games played.

Deviation - Take the team's highest score and add to it the team's lowest score.

Winning Percentage. - Divide the team's number of wins by the number of games played.
The OIL has taken the Oberon Mt. Power Rating Formula and added one wrinkle to better compare teams from different seasons. For example, a 2018 team might have the same record as a 2010 team but more points scored. On its face, the 2018 team is superior. But, if the league-wide scoring in 2018 is significantly more than it was in 2010, the 2010 team may have been more dominant. That is what we aim to discover using the adjusted OIL Power Rating. The formula for the adjusted OPR is:
