Quick startHow to create a survey LOI estimate
1. Choose sample type

Select panel, client, mixed, or not sure. Results stay blocked until this is captured.

2. Add the questionnaire

Upload Word/PDF, paste text, or enter structured survey elements manually.

3. Review assumptions

Check flagged routing, loops, screenouts, randomized items, and open ends before finalizing.

4. Generate and export

Create the LOI estimate, compare point-model and benchmark timing, then export Markdown or CSV.

Sample Type

Required before final LOI calculation. Programmed LOI never receives the client multiplier.

Timing settingsBenchmark model and device adjustment

Questionnaire Input

Used on review/results screens and as the export filename.
