How accurate is the sensor to speed and distance?

Also as i get tired i tend to run slower, will the sensor assume i am still running at the same speed?
As it is only a pedometer will it just assume I'm running at the same speed as i did in the calibration, or does it adjust?

    no it's not a pedometer, it contains an accelerometer. so it records how fast your foot moves and for how long. so with speed and time you have distance.

    I have run everything from 1KM to with this and it's with 20m
    ie I have marked out routes on my bike and then run them and the bike and nike+ within 20-30m of each other (over 20KM)

    So yes I am happy with it.
