So our second level attempt was very good, but I'm unfamiliar with these Intex/Summer Escapes metal frame pools, so I'm not sure whats acceptable, and what is not. We are within 1/2" all around, but do have posts that are not vertically plumb. They were plumb during fill, but settling has occurred, and It appears that the liner (new to us, but now on it's 5th season) has pushed the uprights out on one side (I assume we didn't have the pool exactly centered?) So the entire top frame, while mostly level, is slightly slanted in one direction. I've attached pictures of the pool wall, as well as the four posts around this one bulgy side. I've added a 2" ratchet strap around the bottom to prevent any further leg movement, but is this expected behavior on these types of pools?
