CrazyNewt: If anyone can be bothered to have a squiz over my stats and provide any pointers I'd really appreciate it!
What stands out to me is a fairly low 1 putt percentage. The easiest way to improve putting is to land the approach closer, so working with your irons seems the way to go. I'm assuming you've done a forum search to get advice on wind and elevation. There's probably a CC thread or two that would help.
The best place to get practice in and calibrating irons is a flat course. Beware StA as (at least for me) the runouts can be exaggerated. I'd recommend Pinehurst. Obviously, to get a handle on elevations, you'll need to check in at a hilly course. Congressional is a good venue for this. (Beware #18. The elevation calcs go out the window, there, but the rest of the course is fairly consistent.)
Once you have a good handle on that, I'd suggest looking into how the landing area contours affect your shot. Hopefully, you've learned the trick of changing your stroke to pitch in order to get a look at how the green is contoured.
Good luck. Mainly have fun with it, frustrating as it sometimes is.
