reaches the most people.

TURF (Total Unduplicated Reach and Frequency) runs on your MaxDiff dataset in-app. Pick a reach threshold, Fieldbase finds the item combination that reaches the largest share of respondents at or above it. By-segment comparisons supported. Export the dataset for custom TURF runs in Sawtooth or R.
