What Lewsearch publishes
On the calibrated 50-state benchmark, the average miss is 7.07 points on the best 80% of 1,521 scored questions, and 10.02 points across all of them. Every study is calibrated against published survey data before it reaches you. Enterprise panels are also calibrated to your own past studies, so the numbers line up with the tracker you already trust. The public file is on /benchmarks/states. Lewsearch keeps 650,000 census-grounded simulated Americans across 50 states and D.C.. Studies return respondent-level records, so crosstabs add up to the total, and the same simulated respondents can be re-asked across waves. Audiences can be fit to a client's own data and scored on the client's own past studies. Forecasts are frozen before the official number and graded in public: 3 wins, 1 miss, 3 awaiting a grade. Enterprise workloads run with no external model API calls.
