Reported hold-out performance
Electric Twin reports 95.5% on 1-MAE and 92% on its NDAM measure in its published methodology. Its site attributes independent validation to Professor Michael Muthukrishna at LSE and describes more than 50,000 evaluations.
These figures and the claimed external validation are reported by the supplier. The described evaluation compares response distributions in a held-out test; it is not, on its own, evidence for every target audience or decision context.
