I think computation comes into play more often than one thinks. I think that Kuroko does not merely think of teleporting something somewhere, but also has to consider the mass, complexity (like humans), exact location of origin, and exact location of destination. This makes it extremely difficult to attack moving targets.

For Accelerator, I think he computed practically everything he programmed his power to do, including how much force he wants to add/subtract and what exact direction the vector should go.
