How to read these numbers
Challenge rate is the share of questions that pushed back, pressed for specifics or questioned management’s assumptions. It describes how questions were asked on the calls tracked here; it does not measure whether any view turned out to be right.
Rounding. Rates are rounded to whole percentages, so a small share can show as 0% even when some questions were challenging. The count beside each rate is exact; “none of N questions” means no question was challenging.
No questions recorded. “—” means there is nothing to calculate: no questions were recorded for that period on the calls tracked here. It does not mean there was no activity.
Small samples. Profiles with fewer than 10 questions are marked Limited sample.
Reporting periods. Questions are grouped by the calendar quarter each company’s fiscal reporting period maps to, not by the date of the call. Periods without a calendar mapping are listed separately under their fiscal label.
