When we refer to ahjussi romances, is the age gap 10+ years or 20+ years?

This is coming from me noticing various noona romance dramas having 10+ years difference and wondering if it would be more suitable (for me) to consider them ahjumma romance because of the wider age gap. Some of it might just be that when I hear noona romance I just assume it would be more of a 2-5 year age gap which then feels odd to be compared to an ahjussi romance. I guess this is also because wider age gap romances can have people in different life stages, which again isn’t always what I assume with a noona title. Or I’m making too much of it and since 10+ years is still within the same generation its still a noona romance.
