5Hz would be nice for eliminating the "jumps", and making the movement nicely smooth. But the same effect could be also achieved by a software solution.
To eliminate the lag (the approximately 2 second delay), the software developer would have to implement predictive algorithm.
What 2 second delay? Mine is updated at 1Hz. When I move, it is always t<1sec before I see a move on the screen. If there was a 2 sec delay, if I was stopped it would take t < 2sec to get movement.
