What is the fastest time or shortest duration for reliable setInterval()

Sun 2018.08.26

I have a need for extremely accurate function call timing.

It would be nice to have a range of argument values at:

I'm seeing limitations of the IDE keeping up around 80-100ms

But, as in browsers, faster times might be possible?

What is the shortest reliable duration?

The above pre-supposes all called code would execute before the next call.

Also, need to apply a delay using setTimeout() under the same reliable constraint.
