The one common denominator we have seen, and this is really simple - is that if you want to front run at this level there is one thing you simply can't do - slow down at any point in the race. And it doesn't matter how strong you are, how much better you PR is than the field - in a championship final setting someone will be good enough to take advantage of that inefficiency and will beat you.
I'm glad you mentioned the 2000 Sydney final because the exact same phenomena that allowed Nygeny to beat El G was the same that allowed Wightmann and Kerr to beat Jakob in '22 and '23 respectively. In Sydney they (the Morrocans) tried the same plan as Seville but this time with a different "pacer" and he got it so horribly wrong. In Seville he had Kaouch who went 54.31, 1.52.15 so he was able to keep the entire field above threshold and as the best guy in the race, he survived the war of attrition the best and won easily. In Sydney he didn't have Koach but Youssef Babb who also went out in 54 (54.14) but then ran a horrible second lap of 60.63 which let the entire field recovery and from that point Hicham was a sitting duck (and was lucky to even hold off Lagat for Silver). This is also proof that a human body pacing you is ultimately meaningless if they mess up the pace - you are better off on your own if you can run and hold the right tempo yourself.
But this race was eerily similar to last year in Budapest except it's even tougher for Jakob because he doesn't even get the benefit of someone running in front of him. Jakob lets Kipsang lead in 56.03 (close to Jakobs preferred opening lap pace) but inexplicably runs 58.16 for the second lap and at this point you can throw the 3.27.1 1500m, 7.54.10 2 mile out the window.
I think Jakob can win Paris in more than one way. It's very clear if he can replicate an effort like the other night and simply run each lap faster than the previous - even from a starting base of say 56.0, he's going to win. This keeps the entire field at threshold for the entire race and in this instance nobody can beat him. But I think he can also win from 1000m out but only if he is prepared to really drop the hammer right from the point he makes his move. So this doesn't mean just getting to the front and slowly ramping the pace up. This means at this point he needs to really lean into it (literally and figuratively) and accelerate into a low 55 second lap from which point he simply can never slow down. He's capable of closing a race in 55.3,55.2,27.3 (high 2.17's) off a mixed opening 500m and if he did this I don't believe anyone is passing him.
Now of course the caveat as we all know - doing this with no guidance (aka lights) no matter how good you are is still really hard. Either way the golden rule for Jakob (and I think he knows this and embraces the challenge of doing this) - no breathers, never slow down.
