How a topic becomes 25 questions

Each topic is expanded into about 25 different phrasings of the same underlying question. Each one is asked once, each week.

Why not ask the same question 25 times

Because it would cost the same and tell you less. Asking one question repeatedly measures how much that one question wobbles. Asking 25 different questions measures how often you are named across the way people actually ask, which is the thing you want to know.

It is also cheaper in the only sense that matters: the same money spent on breadth produces a usable number, and spent on repetition produces a precise answer to a question nobody asked.

Why 25

It comes from the arithmetic of confidence, not from copying anyone. Five samples give a margin of roughly ±33 points, which is too wide to act on. Twenty five give about ±18. A hundred give about ±10.

Twenty five is where the margin becomes usable without the cost becoming silly. Going to a hundred would quadruple the bill to halve the margin.
