From the source SKILL.md

The gap between "50 million Americans have disease X" and "how many patients will take this drug" is where most revenue forecasts go wrong. A headline prevalence number is not a market. This skill builds a rigorous waterfall from total disease burden down to the treatable addressable population for a specific therapeutic asset, with sourced estimates at every step. The output feeds directly into peak-sales-forecaster as the patient volume input.
