Your interpretation of the defensive barrier is incredibly different from how it's described. It's really not a random mess, it's an incredibly organized hexagonal pyramidal rotation of projectiles fired at a fraction of light speed. Firing inward in a pyramid or cone shape to intercept projectiles that are on a course for Virtuoso himself, rather than attempting to block every single one of them. The projectiles at the closest point to him fire forward to intercept the radiation rounds before they detonate. It honestly doesn't matter at this point, but that's how it was written.
