Adjusted for current Sagarin rankings:
SEC ranked higher: 5-2; Alabama over West Virginia, Georgia over Clemson, Indiana beat Missouri, Auburn over Kansas State, LSU over Wisconsin, Georgia Tech over Georgia, Arkansas over Texas Tech
SEC ranked lower: 0-4; Florida State over Florida, Clemson over South Carolina, Louisville over Kentucky, Oklahoma over Tennessee
So Sagarin's numbers are pretty close. Each time the SEC team was lower-ranked, they lost. Most of the time the SEC team is higher ranked, they won. That is basically what I was pointing out in my first post had you read it.
But you are not a totally dominant conference if you lose over half your games against other conferences. Doesn't mean you're not better. But not as much better as many like to think (as I also said earlier).
Even if you are totally dominant, this completely depends on which teams are playing which other teams. But yes.
I don't think the SEC is "totally dominant"...but they are clearly the best conference again this year, and it's not a question. It's not like the Big 12 or the Pac 12 are right there as they have been in other years; there's a clear divide.
As for the Big Ten....it sucks. horribly. And if there was a Big Ten - SEC Challenge equivalent in football, the B1G would be destroyed. We'd be lucky to get 4 or 5 wins.
*want to point out this graph is prior to last week, so some teams will shift a bit, but not much
