The SEC wants to put a dagger in the ACC and stay ahead of or on par with the Big10. It knows there are only a few chess pieces left on the board and we are the queen (or at least a rook and a bishop). It isn’t likely to risk letting us to go the Big10. Thus, I *think* we can pretty much write our ticket when and where we want.I remember that chart possibly having significant issues, but I don't remember why.
If the gap is anywhere near that large, I would expect the ACC schools with options to leave as soon as possible. Of course, as has been noted in other posts, the SEC/B1G has to open to new members and I'm not sure that happens until closer to 2030.
Part of the problem with the chart is that future revenue is a pretty guarded number, with just general numbers being discussed. And it also doesn’t account for an elite basketball year like the SEC just had in which it earned $70 million from the tournament. The public gets info that is almost two years dated by the time it is released. Thus, it is very, very hard to definitely state what the ACC and SEC will distribute in 2027 - a problem that is even more complicated with the ACC’s new model (as you point out)
That said, despite all the unknowns, I think it is highly likely that the finances mandate we give our withdrawal notice by next May 31 and we will be in the SEC or Big10 in 2027.
