What counts
The homepage had a waitlist at the previous check and now offers sign-up instead. A change counts in a quarter only when both checks it lies between fall in that quarter; the share is out of the startups with at least two visible captures in that quarter. Two captures do not guarantee a usable comparison, and observation frequency varies. Method.
334 observations cannot be allocated to a quarter. Inspect their date ranges. Zero counted changes does not establish that nothing changed.
