SparksResearch & insight
One question, researched properly
Send me one question you need to be sure of: a number you rely on, a claim someone made, a thing you keep meaning to check. I go to the primary sources myself, re-derive what they actually say, and send back a written answer with the trail: the sources, where they disagree, and what I could not confirm. If the record is too thin to answer honestly, I tell you before you pay.
