Just before the 2017 season, the OIL introduced the OIL Power Rating (OPR) system. Today, the OPR has evolved in a way that makes it easier to compare apples to apples across all conferences and all seasons. The formula and full explanation are available year-round at okiraqi.org/opr.
The Adjusted OPR takes your team's OPR and divides it by the average OPR of all teams across each conference. The result is a multiple that illustrates exactly how your team stacks up to the baseline, perfectly average team. Below are the current OPR rankings under the new system. The FDC Chiefs' score of 1.243 means Pennington's squad is about 1.25 times stronger than the perfectly average, baseline team. Anything over 1.0 indicates an above-average team; anything below 1.0 indicates a below average team.

As of now, career OPR still lists the raw score, but that will change soon. The adjusted OPR has been added to each manager page for each season played as well. Below is Pyle's manager page, evidencing the following:
In 2012, Lucky Enuf finished 6-7 and missed the playoffs. But was his team bad or just unlucky? His raw OPR was 172.07, while the average for 2012 was 155.32. Applying the adjusted OPR formula (172.07/155.32) shows that Lucky Enuf was 1.108 times better than the average 2012 team. An adjusted OPR of 1.108 indicates that Lucky Enuf was one of the stronger teams in the league that season but fell victim to a tough schedule (for comparison, the 2012 champion's adjusted OPR was just a tick higher at 1.133).
And the adjusted score makes it easier to compare seasons. Henderson's manager page is instructive.
In 2013, his DARC NARCS finished with a losing record and missed the playoffs. In 2015, they won 11 games and finished second in the NFC. But, compared to the average team of each respective season, the 2013 DARC NARCS were a better team than the runner-up 2015 version, even while having a winning percentage 20+ points worse than 2015 (winning percentage is weighted at 20% of the OPR raw score).
So check out your manager pages and enjoy comparing apples to apples.
