Provider-reported confidence-model evaluation
Simile reports evaluating a question-level confidence model on roughly 8,600 held-out questions with five-fold cross-validation. It describes Total Variation Distance as the error measure for simulated versus observed distributions, and reports metrics for several confidence-model approaches.
This is a provider-published technical evaluation of its confidence signal, not a universal estimate of simulation accuracy. Simile explicitly says a model may be accurate on average while being inaccurate for an individual case.
