Thanks for getting involved with this. I'm not trying to give you a hard time, regardless of how it might sound (Bucket, on the other hand, may get some grief). You did not answer my questions, but you did shed some light. I'll comment on your post and ask the questions again.
Except for the "Gamer," everyone hits it better on the range. Do you hit it better on range because you hit the same club over and over at the same target? Do you make little adjustments between shots to improve result? Do you feel more relaxed because you can just drag another one over? Are you more comfortable because you know where it will land? Better because you aren't keeping score? I'm not making assessments or recommendations yet, I need more info. Describe your practice routine.
As for spurts of great golf. Excellent, it shows you have the ability. Take heart. Top level golf is allowing those streaks to happen and managing the rest of the round for the lowest score. What causes these runs to stop? Do you keep score in your head or notice your relationship to par while you play? Do you hit a bad shot and try to figure out the cause instead of wiping it from memory? Do you get nervous / excited when you get it going? Do you start thinking about telling your buddies about your great round?
Do you get overconfident and try shots beyond your ability or aim at pins you should not. Do you fail to get up and down from a relatively easy spot? Again, I'm not saying you should or should not do any of these things. I'm merely describing some things people do to interrupt great scoring rounds. When you say you act different on the range and the course, is that more a description of the results or the process?

I am not really certain why I hit it better on the range. I usually go through a large and small bucket of balls starting with my wedges and moving through the bag. Usually hit 10 to 12 drivers and then finish off with my wedges. Because of past swing flaws, (overplane) I really concentrate on hitting the inside quadrant of the ball and driving out to right field. I hit nice soft draws with the occasional pull thrown in. I can go through 100 balls on the range and never hit a hook. But, when I play its fore left!! On a typical round I may hook 10 out of 14 tee shots, 2 or 3 of those will be completely off the golf course. I play like Seve, always scrambling, getting up and down from everywhere, making 4 or 5 par putts per round between 6 and 10 feet. It's truely madness, drives me stir crazy. Generally in a round I may have only about 4 two putt pars. I play high stress golf.
I am a very mechanical player, always trying to fix my swing on the course. I think I need to become more of a feel player. Also, I have a completely different tempo on the course. I can feel my swing getting shorter and faster as I play.
Bucket, when we get together for a round, maybe we should play captains choice.
