Well, Jitter is the deviation from true periodicity of a presumed periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals.
I don't think Ping in MS counts as Jitter because MS is Milli-second, so it means the connection was successfully pinged or reached in 3 milli-seconds, so yea. It's perfect
