The concept of a golfer feeding directly off his worst golf is something we discussed in a feature story in Golf Digest's July issue called "Confidence Kills." As the title suggests, the story also discussed the idea from the other side, which is that a player who feels like he's "striping it" on the range can be injected with more self belief than is helpful. The former U.S. Open champion Geoff Ogilvy described this mindset as a "lazy head space. You just assume you're going to play well all the time."
