Five hundred twenty-four thousand three hundred thirty-four impressions times point eight gives four hundred nineteen thousand four hundred sixty-seven point two, rounded four hundred nineteen thousand four hundred sixty-seven. Bars share zero at point zero zero one pixels per count. Default branch returns the saved fixture exactly, rather than estimating unique users from tracked identities. Saved eight hundred seventy reposts plus seven hundred one replies plus one hundred eighty-four quotes sums one thousand seven hundred fifty-five. Bars compare reposts and replies at point four pixels per event. Source fixture contents and social performance have not been independently verified. One thousand seven hundred fifty-five divided by five hundred twenty-four thousand three hundred thirty-four times one hundred rounds point three three percent. Bars deliberately label distinct scales, point two pixels per event and point zero zero one pixels per impression, and are not directly comparable. Actual complete native export and baseline reset remain checked; reach and viral predictions remain assumptions.
