Sonny, I have done the paper tuning thing in my basement and then have gone outside and done the walk back method on the same bow. In fact my Martin Cougar FC that I shoot now. After the paper tuning I still did some fine movements of the rest.
With my buddy's bow this past year I just went over installed his rest and eyed it up and had him do the walk back, made a couple of adjustments and in no time at all to me he was shooting very tight groups to 30 yards. About a month later he changed to a different rest and did it himself and said it was the quickest and easiest way he has ever seen or done in the past.
Yup ... simple as one can get in my opinion.
