Method
For each question a homeowner asks in the trade's newest weekly run, we take each engine's most-named businesses (the ones named in the most of that engine's answers to the question, ties included) and compare them across engines. Only the engines that named a business on a question take part in it: an engine that answered but named nobody is left out of that question. A question is compared when at least two engines named a business; the questions where fewer than two did are counted apart and not compared. Every engine that named a business agrees when all of their most-named sets share a business; no two agree when no pair of them shares one; a pair overlaps when its two sets share a business, counted over the questions where both named a business. The questions are not published. 8 questions were compared; 9 where fewer than two engines named a business were not. Results describe what was measured, not a promise of ranking.
