One point raised early in this thread-(9 months ago) Has me scratching my head.
One poster says they log each daily trip as a dive rather than the individual dive.
I genuinely don't understand that point. I always though every dry-wet- dry cycle counted as a dive. allowing you get to the required depth and are under long enough.
Goes to the point that "It's your logbook... do what you want with it."
Beyond keeping a running total, I stopped logging dives in any meaningful way about 500 dives ago. So anyone logging "dive days" is still being more diligent that I've been over the past 5 years or so.
