To answer your question, we haven't evaluated the specific amount of time that would be added.
There could be situations where there would need to be evidence added for those points. Generally, the intention is that restitution is supposed to be a very easily quantifiable expense, not one the court needs to untangle, for example, a complex commercial transaction or that kind of thing.
We haven't done this assessment specifically, but it is possible that evidence would need to be heard.
