Well, then one more anecdote:
Back when I was part of a small club DZ, we had a couple 'annual' groups.
They'd come out once a season and do one S/L jump.
They'd take the full FJC, do their jump and disappear until the next year. Each year there were some that didn't come back, and some new ones in each group.
They were all treated as 'first time' students, although the ones that had done it before (and done reasonably well) were given a bit more freedom under canopy.
FWIW, it was out of a 182, one student per pass, and the pilots knew their stuff well enough that they'd be on jump run with the door opening just as the previous one was touching down.
I actually started out with one of these groups, but after that first jump said "I have to do THAT AGAIN".
