430 miles in 30 minutes is a very slow “ballistic” missile.

To me it suggests it did too much of something. I assume that doing less of yhat will get them greater distance. They were 300 km short of lots of Japan.

That’s not a lot.

Yeah thats kinda funny, way to slow for a missile.

North Korea’s Missile in New Test Would Have 4,500 km Range

A 30-minute flight time instead require a missile that was highly lofted, reaching an apogee of about 2,000 km (1,240 miles) while splashing down at a range of 700 km. If that same missile was flown on a standard trajectory, it would have a maximum range of about 4,500 km (2,800 km).
