- Draws the line to closed-won revenue rather than stopping at a lead
- Sending conversions back to ad platforms improves bidding, not just reporting
- Publishes an example showing models disagreeing, which is unusually candid
- Connecting Stripe grounds attribution in the one fact nobody disputes
- Attribution remains a modelling choice, and different models will rank channels differently
