And there it is. I was just about to start looking for this video and share it myself.
This guys awesome! He used to be an engineer at NASA. His squirrel obstacle course videos are also awesome.
I don't think the science experiment took into account TFP pool owners who understand the science of sanitation and are very confident our pool water being able to kill urine very quickly. You think to yourself after 4 beers "should I dry off and go inside? Nah, too much trouble when I know my balanced pool will kill it right away. I follow TFP principles so I'm good".
I kinda wish now that pool math would incorporate that formula from the video so we could all calculate how much pee is in our pool…. Could that be a feature request…maybe a check mark under settings, right under track flow rate? That sounds like a good place to put it…I don't think the science experiment took into account TFP pool owners who understand the science of sanitation and are very confident our pool water being able to kill urine very quickly.

I'm a bit of a lightweight... After four beers, I'm thinking I can drain and refill this pool all by myself..
One thing I think he demonstrated pretty well is that the smell is the CC and not the FC and that there are "forever chemicals" that don't get broken down and don't leave the system.
They measured the amount of Ace-K, an artificial sweetener in many foods and drinks that passes through the human body unprocessed, in the water. Ace-K also isn't broken down by swimming pool disinfectants. [And that's OK, it's not harmful].

They calculated the average concentration of the sweetener in a typical person's urine and used that to extrapolate the results.
So either they found evidence of urine -- or someone has been dumping diet coke into the pools.
But you're correct, the ammonia in the urine would have been long since broken down.
They had to have a catchy (misleading) title to get attention.
Maybe we can get one of the chemists on the forum to help here.

Urine is more then just ammonia. It’s basically all the gunk in your blood that has been filtered out by your kidneys. A certain amount of any medications you take for example will be in your urine. The question is really what all does chlorine break down and should you be considered about what it doesn’t. Chlorine breaks down the harmful stuff… except for a few things like cryptosporidium and I ain’t going there!

I agree they took a little liberty, but I don't think I would go as far as calling it pseudo science. The results are probably more accurate for a community pool than for a residential pool since the population size is larger.
& enlightening...
