Categorized as a "Middle Performer". How do I level up?

I came to know that I was categorized as a middle performer in my recent yearly performance review. This past year, I was asked to lead 2 significant platform/infra projects (teams of 3 engineers). I did exactly that and delivered those projects on time.

I documented the tech specs, helped onboard 2 new engineers on to these 2 projects, provided transparent updates to management, wrote good & maintainable code, and worked with a "customer-obsessed" mindset with application teams to ensure their requirements were met.

Despite all this, upper management still categorizes me as a middle performer. What are things that I can do to increase visibility of my performance and get categorized as a "top" performer?
