good question. Alot of relativists around here doesn't know anything about
overshoots etc. It takes one or two semester theory, and a lot of
experience in measuring plants then implementing PID controllers, in
software, hw and such. You have overshoots if the plant is vibrating
longer than the allowed settle_time. Also, a single overshoot can destroy
whatever target you are trying to control.

But how do you know you have overshot?
What do you know about the original point?
How do you know how close you are to it?

i'm not sure. What are we talking about? It depends on how much a variable
goes off regarding an allowed settle line. Do we undrestain engilsh?

The universe is all a spin-off of the Big Bang.
