You - and many others here - take it as a truth that the three 1500m races and the 5000m heat is a disadvantage for Jakob (and everyone else).
But it normally isn´t. If a runner comes into the championship in good aerobic shape the heats and final in another distance often work well as SHARPENERS and if the last final (as the 5000m final in Paris) is three days after the last race the runner will quite possible experience SUPER COMPENSATION so this last race can be the best in the whole championship.
Dare I refer to my own experience as a elite master runner:
When i participated in my first international champs (European Champs) in my early 50s I first competed in the 1500m where I qualified for the final running a SB of about 5 seconds. In the final I ran slightly slower placing 10 out of 15.
Then I competed in the 800m which was my best event and ran fast enough to qualify for the semifinal which was two days later. In the semifinal I ran a small SB (high 2:08) and placed two so I thought in my naivety I had a chance to medal. In the final (again 2 days later) I improved my season best with about 1.5 second but unfortunately all "the old circus horses" did the same "when the music played" (I am quite certain that every single one set SB in the final) so I ended 7 out of 8.

Other examples I have given in the past:
Peter Snell in the 1960 Rome OG: The internationally completely unknown 800m runner from NZ arrived in Rome with a 1:49.2 PB.
They ran 2 heats the first day!, semifinal the next day and final the third day. Snell set PB 3 times 1 per day and famously outsprinted the heavy favorite Belgian Moens in the final.
PB in the final: 1:46.48.

Recent example: Kerr in 2021 Tokyo OG. Kerr ran a bad heat where he only just qualified on time. You can, however, sharpen even from a bad race so in the semi final he got a "Q" and in the final he ran a great race setting a big PB (low 3:29) and winning bronze.
