Typical range: questions per paper in the middle eight of the ten papers, leaving out the single highest and lowest year (about the 10th to 90th percentile), each paper scaled to 180 questions. The ten-year average and the range are historical fact. The weighted estimate is a model: each paper's share, with recent papers counting more (half-life three years), and dropped syllabus removed. It is a guide to effort, not a forecast.
