In MFN 66 ( https://mfn66.myfootballnow.com/ ) it has my team Cincinnati eliminated from playoff contention a week too early.

my team is at 9-6 awhile Denver is at 10-5 .
neither one of us played each other.
Even KC is at 9-6 though I can understand them being eliminated in that they lost to Denver twice though really they have a better division record and conference record than Denver so I don't think they should be eliminated either just in case Denver does lost their last game and KC and me win our games which I would think either KC or me would get the last playoff spot not Denver.

forget to mention neither Cincinnati nor Denver played each other.

here is the standings

Not necessarily. What's the head-to-head record of Denver and Cincy? That's what kept SD out of the playoffs in MFN-19 despite leading the AC West all season until the final game.

forget to mention that neither Cincy and Denver didn't play each other at all.

What was their records against teams that both teams played?

Conference record is used before common games I believe, so punisher is right here.
