How we perceive rhythmic feel is a psycho-acoustic principle called Beat Induction:-

https://en.wikipedia.org/wiki/Entrainment_(biomusicology)

Our real-time perception of rhythmic feel in the present is hard-wired to the tempo-stability of the events processed previously.

Random variations in the tempo-stability between previously heard rhythmic events is what distorts our perception of rhythmic feel in the present.

Jitter 2001 1B.jpg

Jitter is the deviation from true periodicity of a periodic signal in electronics and telecommunications, often in relation to a reference clock source.

https://en.wikipedia.org/wiki/Jitter

Jitter is more commonly used to report timing errors in very rapid clock sources.

https://en.wikipedia.org/wiki/Word_clock

Rhythmic timing stability can also be reported in terms of jitter.

At a tempo of 120 BPM, continuous 16th events should occur exactly 6000 samples apart from each other when captured at 48kHz.

Maximum jitter values as reported in the tests below are the largest random timing error measured between consecutive sixteenth step events over a continuous sixty second capture period.
