Also, I recall in a witness seeing Dan Chambers sitting on a chair in the middle of the parkin glot with a steering wheel demonstrating shuffle steering (sorry Dan, but it looked pretty funny!), but this in and of itself shows we clearly believe this is too important.....
WRONG!
Sorry Kary, I was NOT using the steering wheel to demonstrate shuffle steering (although it is, as Jad and others point out, a very useful and effective tool). I was demonstrating the difference between smooth and rough steering inputs. 
(Perhaps if you were there and had listened to the demonstration instead of assuming what I was doing, you would have known the purpose of that particular teaching tool. 
Perhaps. What's that old saying ... When you "assume" you make an A$$ 
.... oh well. 
)
As for the debate of shuffle vs. "other," I think it's important to remember that most, if not all Instructors I've worked with as a student, as a co-Instructor, and as former-CDI have all emphasized that the "shuffle" in shuffle steering should occur if your leading hand must go beyond the bottom (6-o'clock) position and your top, or trailing hand goes beyond 12-o'clock position. AND, if the steering wheel must go beyond 180-degrees ( In other words, when the TDC/12-o'clock position of the steering wheel must pass beyond 6-o'clock/bottom of wheel position) you also would shuffle. Variations on this (like preparing for a turn by placing the lead-hand at 12-o'clock and the trailing just above 6-o'clock) can be taught later, with smooth, safe effect. This is still a form of shuffle steering.
I have always encouraged my students to avoid micro-shuffling. Instead, use the entire range of hand position starting at "9-and-3" before "shuffling." That is how countless PCA Instructors taught me (Jad, Ralph, Tom T., Keith V., Lewis W., Steve D., in finitum). IMO: IF it is the safer technique ... especially for new-to-the-sport drivers, THEN it should be considered useful and applied. The determining factor for safety seems to rest with the individual Instructor, from what I've seen.
