I get what you are saying. The fact that you play as often as you in addition to practicing as much as you do makes you a special case The swing, or hit is simply a vehicle...you gotta take it for a spin! The old saw of practicing like you play applies here. I was once told by someone that it took Hogan a considerable amount of time to hit a relativly small quantity of balls when practicing. That is the essence of my point. I would also contend that practice time should be goal oriented. When The Goal is met practice time is over. So in my previous example it is a worthy goal (given the cumulative mess of years of non-practice practice) for me to demand that I focus on just one component for the duration of the session. In fact, it exposed the slighest of sways! My weight was moving to the outside of my right foot INSIDE my shoe. I have a bad habit of buying shoes that are 1/4 size too large in hopes that the feet will be encouraged to grow! The benefits of TGM are inumerable but isolating the stroke into compatible/incompatible components is the genius. Now you can actually work on one thing (OK maybe two) at a time. I leave my practice session looking forward to the next. I have only once thrown a club on a golf course (dear old dad slapped me with a 6 month golfing hiatus) but the driving range has been a heli-pad over the years!
Perfect example today. Drove about 70 minutes to go and play a 7,300 yard course. Didn't hit many balls yesterday as a friend and I went to East Lake to watch the Tour Championship (saw Yoda and said hello). Feet were sore from walking around so much yesterday and took awhile to get loosened up. Struggle early on at the range, then went back to basic, acquired and total motion and brought some new swing feels. Shot 76, on aerated greens and having 4-iron or more on 8 different holes. Hit the ball okay, but that defines consistency. You're not going to be on 100% of the time. You just want to still be pretty good when you're off your game.
