I've played 2 PDGA sanctioned tournaments, and my level during these has been awful. It doesn't help that I was playing while sick (and physically weak) at both of them. But I'm very bi-modal: I play some holes extremely well, and then I go on streaks playing other holes extremely poorly. I oscillate between 990-rated streaks (par machine, picking up a couple birdies here and there) and 850-rated streaks (double bogey time). If I could just figure out how to control this transition, and stay on the hot track, I could compete in Am1 without a doubt. And I think the same could be said about a lot of Am2 players I've been on the same card with, who at times were playing nearly 1000-rated golf but always found a way to screw up the round some place else.
And for me it isn't always a question of course management. I know how to do that, it isn't a problem for me. I'll be playing safe par golf, and for some reason I'll screw up a simple upshot, miss the putt, and then everything cascades downhill after that.
But seriously, my upshots are the glue that binds my game together, and maybe you could use some practice with that. I'm usually excellent in this part of the game, landing within 10' or closer to the pin from 100'-200' out with any kind of garbage to weave through (which is good, because I constantly miss putts further than 10'). Even when I have a bad drive, I can often salvage par based on my usually surgical skills with a Wizard. But when my approach game goes away, its all over for me. Forget it, I'm going into bogey land, no matter how good my drives might be.
Here's something you might consider doing for practice. Grab your putters, and go out to your course on a slow day when there isn't much traffic. Throw a bunch of upshots from the shitty places you would end up with bad drives, and then putt them out from where each lands. Try to get every single one of them in the basket in 2 throws starting from each kind of shitty place. Once successful, make it even more challenging, and go to an even shittier place. Do this on a lot of holes, with anhyzer, hyzer, straight, from a kneeling position, etc., until you have that shit down cold. Anything more than 2 throws is bullshit, and unacceptable. Keep at it until you get that shit sorted out.
This takes the pressure off your driving game. It will give you confidence that you can par out even if you shank your drive badly (unless you go OB, of course). A good drive simply makes your life easier, and perhaps presents you with a birdie opportunity. But it doesn't matter. Then you'll just have more fun, relax, and enjoy the driving game.
