I assume you are thinking of building codes. Unfortunately, they do NOT assume that the maximum per sft live load will ever be present across the entire area, or even in a single concentrated area. You can see this at play in Table 1607.1 of Chapter 16 of the IBC As you can see, point loads considered never approach 12,000 pounds!

As far getting to fill evenly, my understanding is that the only 'trick' is to put the pool on a genuinely level surface. I believe it is the case that the frame pools are more tolerant of out of level surfaces than the Easy-Set models.
