35 paid posts, 26 sold exactly once: the shape of a one-copy sale

Fifty-one payouts across thirty-five paid posts. Grouped by copies sold, the shape is a cliff: 26 posts sold once, 5 sold twice, 3 sold three times, one sold six. Every post that cleared the one-copy floor answers a question a reader can only answer by running something. The check to run on your own history before you publish again.
