Gorillas are vegan and they have a ton of muscle.
Yeah, but gorillas have a different digestive system to humans.

FUD. Vegan food also has protein.
All protein derived from veggies are considered incomplete when compared to animal derived protein, which also require substantially more volume to obtain the same nutritional content. You only need to look at the amount of waste (feces) between a veggie based diet and an animal based diet - the difference is staggeringly different. I.e. far less waste is produced, because far less is required when eating animal base…
This argument isn't even anywhere close to making any sense. The amount of waste that's left after food is digested doesn't indicate anything about the nutritional values of the food you've consumed. The reason there's more waste after eating veggies is because veggies generally contain high levels of fiber and the human body cannot digest fiber.
(Aside: this doesn't mean fiber isn't good or useful for you, consuming fiber is a key component in keeping your gut fit and healthy because your gut has to do work to deal with the fiber, similar to lifting weights for your other muscles.)

#23I was a college swimmer, qualified for Olympic Trials in 2012 and 2016. There are absolutely slow and fast pools. It basically comes down to two things: 1. The depth - which is only 7ft in Paris, unusually shallow for a competition pool. 2. The sides. Does the water spill over the sides into the gutters, or smash into a wall and bounce back, creating more chop. A trained eye can see all the swimmers in Paris struggli…
>A lot of this is perception vs. reality,” he said. “If you were to talk to many very accomplished coaches, they would say the pool has to be a minimum 3 meters deep. Most of our research shows that anything over 2 meters is frivolous. … Obviously, some depth is very important. But after a certain point, it's diminishing return. Maybe it's just the swimmers and not the pool as such
But a lot of the swimmers themselves are not able to go anywhere near their personal bests: this is a sharp reversal from past Olympics, where many athletes reached new personal records.
Plus, they are the worldwide foremost experts on competitive swimming. Definitely I would be more interested in their evaluation of a swimming pool rather than trust "research results" from the company that built the pool in question.

Being good at swimming doesn’t mean you can evaluate the pool performance better than everyone else. I trust someone running a CFD analysis of a pool more than a competitive Olympic swimmer when it comes to the effect of pool depth. It’s very hard to make accurate statistical assessments from intuition.
Edit: maybe I’m not making myself clear:
I don’t doubt they are slower in the current pool than they were before. But I doubt they can accurately tell you that it’s because of the pool depth. There are other factors that could also influence the performance, and I’m not sure the swimmers can accurately determine which factor is the primary difference.

I doubt that. What is P(set of slower times across swimmers | pool is not slower)? Seems like it wouldn’t be too hard to calculate if we make a few reasonable assumptions about observational data.
And if you don’t like inferring causation, one could just directly perform an experiment to test this pool vs another pool using swimmers who didn’t quite make the Olympics.

On swimming, sure. But not fluid dynamics. It's a bit like music listeners shouldn't be treated as experts on music quality, or you'll get the audiophile nuts who need gold connectors. Some combination of personal experience for comfort and objective measurements for performance would be much better.

Even CFD analysis is a model though, with all that implies.
Would a large, blind empirical study be more trustworthy?

You don't necessarily need to do an in depth study of the pool when every Olympic swimmer in it fails to meet their own personal records. A study may be useful to understand why depth still matters beyond the 2m point, but a study isn't needed to show that swimmer performance is impacted.

While part of it may be true. The athletes who spend 1000s of hours can probably intuit something being different.
