After watching gun camera films of rocket attacks on buildings and shipping during WW2, it appears that there is no convergence to the rockets. In fact, when launched with minimum intervals (or all at once), they appear to fly in formation with slightly diverging flight paths toward the target(s). Now that I think about it, there seems to be more good-quality film footage from British rocket attacks than from any other country. Lots of Beaufighters and Typhoons.
