Stinker . . . here's a thought . . . how about purchasing a net for your "tinkering" mechanics practice . . . . and spending your hour at the range playing shots rather than mechanics. Use more of your range time to really practice like you play. Go through your routine change targes and clubs. Practice at a slower pace . . . the game is SLOW between shots so try not to hit and rake.
Bucket,
Much wisdom in this post. The reason why golfers CAN'T take it from the range to the course, because they never take it from the course to the range. At least fifty percent of your practice should be as you have described.
