I always check the pulse response, because nearly all of my
designs have requirements in the time domain like settling time.
When it comes to PID controller you definitely need the transient
analysis due to the nonlinearities caused by the possible saturation
of your integrator and/or differentiator. This does not mean
that the circuit didn't regulate, even with saturation, but the
behaviour wil be much different from the linear model.

I don't understand any rule of baseball, but there is a
baseball team in the town I live.
I will read the rules tomorrow. It's the part "Regelkunde".
