He presents some extremely simplified mathematics to explain how hypersonic missiles maneuver and how they are intercepted.
What worth noting is picrel. AA does not capable to intercept within a circle. Depending on speed and the angle how the missile enters into the range of the battery the interception area is reduced and deformed in extreme fashion. Interception works most efficiently if the rocket is heading directly towards the launcher but that's rarely the case.
So if we wanted to cover everything... that's just not realistic.
