Study 01
How much warning do students actually get?
This study is still accumulating. It measures the gap between a listing appearing on a platform and its deadline, which needs a stamped daily archive rather than a snapshot: you cannot tell when something was published by looking at it today. The archive is filling now, and the first sample worth publishing needs a couple of weeks of it.
Nothing is estimated in the meantime. A page of plausible numbers would be worth less than an empty one, since the entire value of a figure here is that it was measured.
