Not sure anyone can honestly answer your question without a ton more info (if at all, really). But for perspective, have a look at some old data shared by Nate including w/kg info for men at a range of ages.
Regardless of age & training history, 4.7 w/kg is rare air that is held by very few. I’d be cautious about setting such a grand target without knowing more about you or why that is a particular goal.
