wings08 as some one who hasn’t yet been to 30000 as the pilot, I am guessing you would need roughly 75 give or take miles for a nice smooth constant descent. Would that be close? Maybe some speed brakes. I would guess there would be airframe specific procedures as well.
Traditional 3 to 1 rule says 90 miles, assuming the destination is at sea level. Most modern planes will give you a visual cue for TOD.
