This reminds me of the quote by Henry Ford when he said if he had asked people what they wanted they would have told him "faster horses". Sometimes users don't know what they want till you give it to them.
This is the reason that I said DATA (that you measured) and user feedback. Furthermore, I am talking about the funnel, incremental changes. Ford probably got user feedback to make the car better. What you said comes before.
