MWITA-SBO-2026-012 · Evidence B · P1
Data-augmentation targeting increased salesperson-meeting requests for a Spanish solar advertiser from 6.80% to 7.79%, a gain of 0.99 percentage points or 14.6% relative.
What this does not establish
B2C Spanish homeowners over 35; outcome is a request to meet a salesperson, not a completed sale or revenue.
Counterevidence & uncertainty
Data augmentation materially worsened offline accuracy in the hearing-aids segment, so the method did not improve every product domain.
What would change the reading
Track replication, revised records, denominators, confidence intervals, context changes and deployed commercial or human outcomes.
