- Lance: [Initial Delay] affects each model itself.
  - [Initial Delay] is chopped off from the front of the waveform.
- Bob: The question is about [Initial Delay] in [Submodel]
  - A [Model] could have both [Driver Schedule] and Add_submodel.
- Mike: We could decide that [Submodel] will not have [Initial Delay].
- Bob: We would have to say that in the spec.
  - It is desired to have it.
