NPS equals the percentage of Promoters minus the percentage of Detractors, with Passives kept in the denominator; bands and formula per Bain's Net Promoter System documentation. The margin of error is a normal approximation calculated from the response counts themselves, using Var = (p + d − (p − d)²) / n with p and d as the Promoter and Detractor shares
