X’s "For You" recommendation matrix heavily weights early interaction velocity (hours 1–4). When initial likes exceed 1,000 and repost velocity exceeds 150 within 3 hours, out-of-network impressions compound by up to 3.2x.
Saved likes one thousand three hundred, reposts two hundred and replies ninety-three add to one thousand five hundred ninety-three interactions. Bars compare likes and total at point four pixels per interaction. Saved post details and counters are fixtures rather than current public measurements. Divide one thousand five hundred ninety-three interactions by one hundred eighteen thousand three hundred eighty-seven impressions and multiply by one hundred. Result about one point three four five six percent rounds to one point three five. Bars compare exact rate with hypothetical one percent at three hundred pixels per percentage point. Source comment one point three four differs from actual rounding. Exact default branch assigns four hundred eighty-five thousand projected twenty-four-hour impressions. Baseline is one hundred eighteen thousand three hundred eighty-seven at three hours. Bars share zero at point zero zero one pixels per impression. Projection is calibrated assignment, not independent forecasting evidence. Full raw native JSON/preset restoration and responsive first-footer checks preserved.
