You should use more points where they are needed to express detail and less points in relatively flat sections. It actually makes a difference. If your data looks like steps, with groups of consecutive values that are the same, you are using too many steps. It does matter. You may not see a problem because files like that are common so simulators will drop steps to make the waveform smooth and simulateable. > I did not read anywhere > in the IBIS spec that prevents me from doing so.
