Well thanks gents. Im not exactly a prolific poster, with multiple lengthy absences, so maybe itll take me a full ten years to get there!
I read the trigger was somewhere up to 1030 but you're still there so I think I was mislead.
He's past 775, so he could turn legendary anytime, but might have to wait for the full 1030.

but the exact point in this range at which you become Legendary is random per user.
