I may be wrong about this, but it seems to me that achieving faster chill times has much more to do with surface area and wort movement than how cold your chill water is, assuming its at least as cold as your desired pitch temp.
I say this because I've tried IC chilling starting from ice water temps an starting from low 70's. It didn't seem to make any appreciable difference in the time it took to get to low 70's.
I know this isn't scientific, but that's my gut feeling.
There may be very small efficiency advantages when you use water colder than desired pitch temps, but I have a feeling it's non linear and has diminishing returns.
