 "reading": "The bids with a source posting date are not a random draw from the cleared bids. They lean toward portals that publish a posting date, and the platform mix of the two groups differs (distance 0.34 on a 0 to 1 scale). Two checks bear on whether that moves the answer. Bids with and without a posting date stayed open for almost the same time after we first saw them (13.0 and 12.8 days). And five alternative cuts, including re-weighting to the platform mix of all cleared bids, put the median between 23.5 and 26.0 days. We read the window as about 24 days for the cleared sources, and we have not measured it for sources outside the cohort.",
