It's kind of a mixed bag. It's worked okay for me if changes are truly minor, but if there are large changes to the logic it doesn't seem to be very good about "forgetting" what it learned from the previous pass. Three or four times this week I've had a design fail to make timing with SmartGuide, but work when doing P&R from scratch.
