This is a branding problem.

Calling the model ‘calibrated’ or ‘honest’ or ‘humble’ suffers from what is called out: people don’t want a humble answer of ‘I don’t know’, they want a solution to their problem, confidently delivered so they can trust it.

Call the calibrated model ‘business mode’ and the guessing one ‘consumer mode’, problem solved… in as much capacity as possible without regulation.
