I've just released an update for the Repeat Customer Insights demo site to include a larger number of products and variants. Now you'll have better examples of how it analyzes products and variants.
I ran out of fun product names and silly puns for the demo data so I only created 16 or so products. I've seen actual stores analyzing many more products with the app (one store has over 500,000 products).
This update should make it clearer for CPG stores to see how products contribute to customer behavior.
