Shaved to 4/32nds or so is the consensus. Worn to 4/32nds isn't the same thing, mind you (the significant heat-cycling to get to that point while wearing on the car negates the benefits of shorter tread).
I'd say anything past break-in to 3/32nds or so would be prime. These things are only 8/32nds new, they don't have much tread squirm at full-depth.
