Some good points.

Having done OLS statistical analysis for complex econometric models, I can say that subgroup stratification doesn't take much more time. With sophisticated statistical software packages like SAS it takes a couple hours. With Excel, it takes a couple more hours. This is not to say that data analysis only takes hours. The marginal difference in stratifying data among multiple cohorts is only hours. The entire effort can take weeks, and then there is of course weeks for review and audit.
