Did your tender explain why those 3 minutes matter more than they look on paper? I had a similar thing happen on a pipeline job where an old hand told me the tables assume everything goes right, and nothing ever does. I started logging real times down to the minute and adding a small cushion before the chamber, and it saved me once when the boat lost an engine and we sat on the surface way longer than planned. The deck hands grumbled about the extra wait, but the DMT backed me up, and nobody argues with a guy who can show his math.

Wait, you mean you've been going since April and only noticed when you actually sat down and counted? That's kind of the whole thing right there, because the journal becomes this living record and you stop seeing the forest for the trees. It makes me wonder if tracking the page count itself would change how you use it, like once you know you're at 50 do you start treating 100 as some kind of goal and rush spreads just to hit it? Half the fun of a bullet journal for me is that it never tells you how much you've done until you look back, so adding a running tally might mess with that. Then again, maybe seeing that 50 would push you to actually finish the half-empty collections you've been ignoring.
