For me depth is a function of the purpose of a given dive -- most of my 360 dives are fairly shallow shore dives where the reef starts at the surface and goes to the bottom -- 30 -40 feet. So, for those dives, the maximum depth is "no deeper than the bottom"
On the other hand, I've done deep dives to learn specific skills or to look at a specific attraction. My deepest is 141 FSW -- the purpose was to explore a colony of long armed lobsters that lived under an overhang at 135 FSW.
