Most people don't exploit the full capacity of their bodies and so would never notice, which is essentially the point OP is making. This disease very likely ravaged the 20% claimed, but the vast majority may never know because they're just never pushing their bodies hard enough.
If anyone wants to quantify this then Athlinks is a good place to start for race results. Obviously the data is somewhat noisy, like you'd have to throw out the slower finishers who maybe weren't trying hard. But if there's a significant correlation then it ought to show up.
If long COVID disproportionately affects people who are sedentary, then you won't see that in endurance athlete performance.
Poor performers and no shows are exactly the population you’re looking for. To be clear the argument isn’t about a 10% decline across the board among people with long COVID as there’s non cardio pulmonary symptoms like brain fog, loss of smell, and difficulty sleeping.
If 80% of the fit population had COVID, 20% of them had long COVID, and half the people with long COVID had a 10% decline in race performance. That’s something like an overall 0.8% drop of performance assuming nobody dropped out or joined, but again you’re loosing people on both sides who were most impacted. Thus I’d be highly skeptical of finding an actual connection here rather than something else that impacts more people.
A more useful approach is to take a cohort of people who raced in 2019 and track what happened to every single one of them specifically.
The PVCs, adrenaline dumps, sleeping problems and anxiety/panic were insane! The doctor thought that my hypothalamus was inflamed because of COVID.
When you mention “adrenaline” was this somehow tested or just a frequent feeling of being stressed when you had no reason for such?
I find finding the right type of specialist isn’t always straightforward and even when one does, about 80% of the time they aren’t interested in diagnosing anything not blatantly obvious…
After 5 years I would happily trade only a 10% performance loss for the days and nights full of nerve damage pain (neuropathy)and what seems to be 30% performance loss
BTW very relevant to your daughter's story:
the first year of long-covid I was absolutely certain I had permanent lung damage and started searching everywhere for solutions
There are two possibilities that might be hopeful for her
The first is that it might not be permanent alveoli damage (which do not regenerate in humans) but rather obstruction from a "hydrogel" that forms during active covid and takes many many months if not years to dissipate entirely

The second is much more serious and not available in the United States except experimental trials for other diseases
2. "Inhaled Tissue Plasminogen Activator" or "Nebulised Rt-PA"

BUT there's something you can try right away
see this table of plasminogen activators

at the bottoms is Nattokinase and Serrapeptase
which are simple enzymes, you can buy Natto-Serra on Amazon and very very slowly perhaps over many months it might help her lungs (this is just a guess)

I didn't go into too much detail in my original post, but we think this is likely what happened to my daughter. Post-COVID, she could still go for long durations at 80% but when she pushed her limits, she would hit a wall and start to experience asthma like symptoms along with the feeling like she had mucous in her lungs that she couldn't get out. It took close to 2 years for her to stop experiencing those symptoms, at which point her competitive running peers had passed her by. She's happy to be able to enjoy running again but she did lose out on the competition part.
