Good latency. Or the time required to communicate between two spots.
Human reaction time [averages around 250ms](https://spectrum.ieee.org/enabling-superhuman-reflexes-without-feeling-like-a-robot).
End-to-End (any computer to any other computer) is more difficult to gauge, as there are countless different infrastructure considerations between those two points.
If you’re using modern cable/dsl it’s probably between 30ms-60ms range.
But still about 5 times faster than it really needs to be, this allows for a lot of redundancy, so that even if you have something like packet loss or transmission errors, you can still retransmit and have time to do any needed calculation.
It’s still not perfect and depending on the error handling software can range from great, to not as great.
