Forgot to comment on this one.... the time it takes for tracking is a function of your program which runs a loop about 40 times a second (25 ms) for updates... the latency of the sensor is probably negligible. just remember, (last I heard,) if you exceed 5 delta_t in your program... your robot's gonna shut down anyway so you can't take readings at a longer interval than 125 ms and still have a running robot.
I could be mistaken on the amount of time the program runs... if anyone has different numbers I'd love to hear them.
