So it's more shallow, which is a problem. Like if you trained for track on pavement vs rubber vs sand, you're going to have different results, even if "everyone has the same environment" not everyone's body will have the same relative response. I don't like that assumption that just because it's the same for everyone means the difference will affect everyone the same.

Are France competition pools across the country just always that shallow? What are dimensions of the pools from the past 10-15 Olympics? Should this have been an established standard? (gonna say yes to that one)
