Is OPR an accurate measurement system?

[CJ_Elliott]

First off, I would like to start this with a warning. I am NOT trying to degrade any teams or try to say that they are not as good as they were, and i fully understand that teams do their best in this competition and I am proud to be able to associate myself with these teams.

Now. I don't know exactly how OPR is equated. But right now I am seeing a lot of people looking at OPR more than anything for finding the best teams in FRC.

Im looking at Northern Lights specifically because my team was there. But TBA has teams with OPR's that are significantly less than they should be. 5232 for example, was breaching their defenses with about half of the match left. Now. The lowest OPR out of the 15 is 28.27 points... now. The largest miss in my mind is 5232 (Talons). Lets say 5232 was challenging (which they were), and breaking 3 defenses (which they were). Even outside of elims where you get 20 points for the breach, their contribution to their alliance is 35... 5232 isn't even in the top 15. Now i get that there can be problems with a system but in Northern Lights alone I can come up with 5 or 6 teams off the top of my head that should be ranked higher.

So if someone could explain this or help me understand how OPR is this amazing system for ranking teams when I am not seeing it accurately representing teams, i question it's validity. (And I highly urge people to watch Northern Lights and see once the videos come out)
