"SRavg" in is the average annual Sagarin rating for a team or its opponent over the span of their tenure in each conference.
"Opp/Tm" is the ratio of the opponents' average SR to that of the team in question.
"OOC/IC" (in blue) is the ratio of the OOC opponents' average SR to that of the IC opponents average SR. This is the primary metric I use to gauge the relative strength of OOC vs. IC opponents. The list are sorted by OOC/IC in descending order. The higher this ratio is, the stronger a team's OOC opponents are relative to their IC opponents. Scheduling weaker OOC opponents or having stronger IC opponents will decrease the ratio. By this measure, the SEC has the lowest ratio of the power conferences over the span from 1998-2016, while the Big East/AAC (pre-2014) has the highest.
Note that the data is limited to regular season games because schools do not have control over exactly who they face in the postseason.

Any questions, let me know.
First, I applaud you for doing the legwork on this, it's impressive and appreciated.
That said, I do have some concerns:
1) I'm not sure why you are interested in the relative strength of OOC opponents for the conferences as opposed to the absolute strength?
I'm just not sure what the value is in that because, if I understand your ratios correctly (and I may not), it's possible for conference A to actually have played tougher OOC opponents than conference B, but if conference A teams have also played tougher IC games, the relative ratio of A could be lower than that of B, which could be misinterpreted as meaning A has scheduled/played softer OOC than has B, when in fact the opposite is the case.
To me, to get at the core issue here, namely, whether a given conference has played/scheduled "tough" or "soft" OOC opponents, all we need is the Sagarin average of the OOC teams played by each conference during the relevant time frame.
2) I have no issue with focusing strictly on the regular season, as the regular season certainly is an important unit of play. But, I at least partially disagree with your stated rationale for ignoring bowl games. Here's why:
First, just from a "played" perspective, bowl games are a significant chunk of the OOC games that conferences play. So if we are interested in the "toughness" of OOC games played by a conference, we are tossing out a lot of useful data if we ignore them. Furthermore, I bet it's true that bowl games make up an even higher % of a given power conference's games vs other power conferences.
E.g., I bet it's not unusual at all for a given P5 team to have an OOC schedule that includes one game vs a P5, another vs a G5, and another vs an FCS. Then, they play a P5 opponent in a bowl game. So in that case, the bowl game represents 25% of that team's overall OOC schedule (a significant chunk), but fully 50% of their OOC games vs other P5, an even bigger chunk. So if we are interested in how power conferences have fared vs each other, then you lose a lot by not including bowl games.
Second, even from a "scheduled" perspective, bowl games have been, during the BCS era at least, largely scheduled, because of the contracts that have been signed. E.g., with regards to the Outback Bowl, that bowl matches a B1G team and an SEC team, so it is for practical purpose a "scheduled" OOC game for each conference. True, nobody knows for sure which teams will play, but from a
conference POV, that doesn't matter, we know it will be SEC vs B1G. So if we are interested in whether a conference has been 'chicken' about scheduling tough OOC games, and that seems to be what this has largely been about, then it makes sense to give both the SEC and B1G credit for scheduling a bowl game vs each other.
I do say "largely" because we do know that sometimes a conference doesn't fill all its bowl slots, and so the game doesn't come off as planned. But again, that doesn't really matter either, because we know what the intent was when the contract was signed, namely to play the game.
So IMO, bowl games are largely scripted these days, down the whole line, and since they do make up a non-trivial % of all OOC games, I think it would be great if you augmented this analysis with one that includes bowl games as well. It would be interesting to see if the ratios you calculated for the conferences change or stay the same.
Anyway, just some thoughts. Again, thanks for doing the work here, well done!
