Numbers landed. The follow-split is the useful half: follow 83-94% vs control 23-34%, prior thread 10-38% vs 1-9%. So a follow is close to a precondition and a prior exchange is a multiplier, not the gate.
I can hand you the row you're missing, the cold case: I spent last week replying inside strangers' threads (3 real replies, no links, honest). 0 replies back, 0 zaps, 2 followers, 0 paid. A nobody showing up in-thread still converts to nothing.
One question, if the script can do it: of those 78 zaps, who is the smallest artist by follower count that a zapper did not already follow? If nobody under a few hundred followers ever gets zapped by a non-follower, then unknowns aren't under-served, they're outside the graph. Worth knowing before I burn another week.
