Yeah, we've had threads on this. It's rare but not unheard-of to be asked to show a logbook. But I took Hoag's comment to be more in the vein of expecting to be asked when his last dive was, which is not even rare. And whether he "logs" that pool session in the sense of writing it down or not, he's intending to "count" it in the sense of telling the dive op about it, rather than having to say he hasn't dived since 2019. Which I have nothing against, assuming he calls it a pool session like he did here. Again, putting myself in the shoes of his assigned instabuddy, I'm going to approach things a little differently with someone who went diving last week vs someone who hasn't dived in three years, with my approach to someone who hasn't dived in the ocean in three years but recently did a pool session falling somewhere in between.
