ESPN's FPI has Florida State ahead of Washington as well.
Now you're just throwing spaghetti at the wall by looking at ESPN's FPI. https://www.espn.com/college-football/fpi
The top 3 teams are Michigan, Ohio State, and Penn State. 
but that is sort of the point I was making. There is so much subjectivity in how they do it, which doesn't make sense
If Georgia would have beaten Bama, would FSU or Texas have been the 4th seed?
It's an interesting question. Texas's win over Alabama would have meant less; instead of the giant killer riding a 12 game win streak, they'd have been a two loss opponent. It would have been justifiable to put FSU over them, although I think Texas is a better team currently.
a 2 loss opponent that needed a miracle to beat a 6-6 team.
I don't think there is a question FSU would have been ahead of Texas in that scenario, which also means they should have been ahead of them right now. Even losing to Georgia, Bama would have been the best win between Texas and FSU as Bama beat LSU (FSU's best win). The next best opponents were Louisville and Oklahoma, but OU beat Texas. Okie State and Clemson were ranked similarly, KSU did squeeze in at 25 giving them the extra ranked win, but KSU lost to a team that lost to Ohio.
FSU beat more bowl eligible teams than anyone else this year, they just didn't have that super marquee win to boost the schedule strength and also played more of the really bad (as opposed to mediocre) ACC teams, also bringing the schedule strength down some.
The committee was so fixated on the week 2 win, they didn't do their job properly. Michigan should have been 1. Washington and Florida State should have been 2 and 3 (I think you could argue either order). Alabama should have been 4. Bama played a much more difficult schedule than Texas. They have a comparable top win and a better loss, but played and beat a lot more ranked teams. And it isn't like Texas has been crushing everyone. Since losing to OU they have a 7 point win against lowly Houston, a 3 point win against KSU, a 3 point win against lowly TCU (remember tcu lost to colorado), and a 10 point win against Iowa St, along with some bigger wins against lowly BYU, mediocre TTech and Okie St.
