I've stopped doubting Jakob. This is a man who ran a 3:31 1500 as a 17 year old, easily won the Olympics and toyed with a great 5k field last year. He fears no one after years of battling Africans. He has Michael Jordan like confidence and intensity.

That's Yared, not Jared. But yeah, I agree that if someone actually has top-level training development like Jakob (or like Jim Ryun starting older but going for it and not waiting for a lifetime peak), they will be in their peak starting by the late teens. Natural levels of the important 'performance' hormones like HGH and testosterone all peak before age 20. That peaks in running are often delayed beyond the early 20s is due a slower approach to training development, not that the is body physically most capable later. In swimming, you'll see a lot of athletes reach peak in high school because the body is fully capable then, and they're not worried about impact recovery.
Also, if we are talking actual peak age of competitive runners, most people that race in high school and college actually do peak in their teens or early 20s because very few of them are as motivated after graduation.
Jakob hasn't peaked yet. Most athletes will reach their physical peak between 26 and 28, and that's irrespective of how young they were when they started training. That Jakob had a heavy load from age 10 is only an advantage for him and leaves everyone else playing catch-up. With modern sports science, he could be at the very top into his early thirties - just look at LeBron, Messi, Ronaldo, Djokovic.
The biggest impediment to Jakob staying at the top is mental burnout but becoming the only three-time Olympic champion in the 1500 seems to be a big motivation for him
23 is the average peak age by PR amongst top 100 male athletes in every discipline under 10k. Do some research.
Jared and Jakob are most likely in their prime right now.
That's partly because you're including athletes who are still competing and we can't know if they've peaked, and you're including multiple performances from the same athlete, you should use the WA list instead. Let's just take the top 10 1500m all time list and age they set their PB (excluding those still competing as it's impossible to know if they've peaked yet):
1. El Guerrouj 23
2. Lagat 26
3. Kiprop 26
4. Morceli 25
5. Kiplagat 24
6. Ngeny 22
7. Makhloufi 27
8. Iguider 28
9. Manangoi 24
10. Farah 30
Average age: 25.5
I'm not doing the top 100 but other notable athletes by age of PB
Coe 29
Maree 28
Willis 32
Aouita 25
Centro 25
Ovett 27

Jakob didn't get better from last year to this year (yet). Jakob ran 3:30 indoor 1500 last year, this year he set up an attempt to potentially beat that and ran, what, 3:32? Yared improved a lot this year setting multiple PRs and is now arguably equal to Jakob's fitness. Let's see if Jakob cranks it up a level outdoors and if Yared still has more in the tank for another step up outdoors.
