Dirk, that's a conversation wormhole that I wouldn't want to spend the time or effort to work through. I love my trade, but I'm unwilling to (again) put for the time/effort it would take to change an ENTIRE industry. My priority is making MY customers happy, not my competitor's customers happy. Heck, I only joined this site to help the consumers of MY industry enjoy the pools we enjoy providing. That is the time/effort I decided to put forth to help my industry's consumers enjoy more.
We get customers asking to help them build their pools themselves all the time and 99% of them have no idea how many aspects that are important to a proper pool project. It's not easy. I'm not perfect, nor will I ever be, nor will anyone ever be. Some profession's are easier to be closer to perfect than others. The profession I chose to support my family, and the families of the 8 employees I have, happens to be difficult to be perfect. I'm OK with that and I'm OK with the amount of customers that are happy that they chose us to build their pool.
Now please don't make me regret even attempting to help the OP understand why it's not an easy fix to get an entire industry to change and start using BOTH water depth and structure depth. I just wanted to help everyone understand.
