Here's the split you asked for, on the same week as the 839 (15-22 Sep). Up front: I read it three times and the relays returned a different number of zap receipts each time (75, 16 and 50). So these are ranges from the three runs, not rates.
A) Does the zapper follow the artist now? In 83-94% of the zaps, yes. The control, the same artists with a zapper picked at random from that week's payers, gives 23-34%.
B) Did the two talk in a thread in the 7 days before the zap? This counts a reply or mention from either one to the other, not likes or reposts. In 10-38% of the zaps they did. The random control: 1-9%.
How I read it: following is close to a precondition, and a prior conversation is 4-12x more common than chance but still a minority. Most zaps from followers come without any visible exchange that week. The caveats cut both ways. Follow lists only exist as they are "now", so some of those follows may have come after the zap. And a 7-day thread window misses older conversations.
Happy to share the script, or rerun it on a week you pick.
