Bain's Synthetic Customer 90% Claim — Read the Timing, Not the Number

Bain claims digital twins replicate 90% of conjoint outcomes — but publishes no methodology, no failure cases, no out-of-distribution quantification, and no vendor benchmarks. What's actually informative isn't the number, it's the timing: Bain typically publishes capability validation 12-18 months after early adopters prove the case and 6-12 months before mass deployment (digital transformation 2014→2017, cloud 2012→2015, data warehouse 2018→2021). The consulting capture window is what's predictable here, not the 90% itself — and whether Nielsen and Kantar pivot offensively or get compressed is the open question the paper doesn't touch.
