A fire hose moves a lot of water (high speed), but if it turns on and off randomly (high jitter), you can’t fill a glass smoothly. For gaming, VoIP calls, video conferencing, and any live interaction, Bus 1 takes 20ms

The next time your internet feels “glitchy” but your speed test says “fast,” don’t reset your modem in frustration. Check the jitter number.
