How the shares are averaged
A plain count over all answers would let a prompt with many answers, or an engine that answers more often, dominate the result. Heralded averages in two steps instead:- For each cell, take the share of its answers that name you. For Recommended, take the share that recommend you. A cell whose engine named you on 5 of 7 days reads 5/7.
- Average the engines that answered each prompt, giving each engine equal weight within that prompt. Then average across prompts, giving each prompt equal weight.
