Foot Pod - how to show current speed

Hi ... maybe stupid question ... I have the Garmin Foot Pod and I have the feeling that the speed/pace that I'm seeing on my watch is some average (maybe over 3/5s). I don't see instantaneous change in pace when I do several fast steps. Is there some way to get the pace more accurate? I was hoping that the pod will help in interval training but so far it is not all that much better as I still don't see current speed with high refresh rate. I would think that the pod can provide change in pace for each step. Or not?

Thanks!
