This is going to scoot way above the preferred mathematical levels of most readers, and that's fine. The reason for sharing this is that folks wonder why their $40,000,000 business isn't growing while Stitch Fix went from zero to a billion in sales in no time at all ... now granted, Stitch Fix needs humans with taste and they need cute merch ... but they also leverage math. And they tell you what they're doing ... almost daring you to copy them.
It's all there for you (or for you to get Cohere One or Belardi/Wong to do for you) ... just copy them ... you keep asking me for best practices, well, go get your favorite catalog agency to copy this for you. Just ask them.
