I'd say that level of precision and driving that distance has been shown before.
Not sure anyone is around that still remembers this, but we scored 2 tubes in autonomous in around 12 seconds here back in 2007 (Old camera tech took ~3s to lock on to the target as the rack was moved between matches).
In an offseason match:
910 Double Keeper at ARC
In an offseason practice match:
910 double keeper at marc
Returning very accurately to a known position is easy with wheel encoders as long as you don't slip (the hard part). Considering the best high shooters will probably be able to make a 20 ft shot, they wont even have to drive more than 10 ft (x3) even at a slow 5 ft/s the driving ony takes 6 seconds. 9 s seems like enough time for decelerating, gathering, and shooting two balls.
Now I wont be so bold as to say it will happen all the time, but I think we will see it before the season is out.
