Ambiguity
When wording can reasonably be read more than one way, leaving the reader or AI to guess which meaning you intended.
Say it to an AI
From the attached export, count August active users, where 'active' means at least one login and at least one logged workout in August; logins alone don't count. Give the count, the share of all logged-in accounts, and how you filtered.
How an expert would ask for the stronger version of “Monthly active users”.

Why: 'Active users' could mean any login or real use; B's reply silently picks 'at least one login' and reports 3,910.
