People please, is all this really necessary for a computer game. Very, very nice for someone to take the time to do this, but really. I have never seen anyone in real golf, lay out a gauge or any other device to measure their putt. I am getting close to making legend, and have never used a single tool to get here. No notes, no gauges, no calculators that make me take 60-90 seconds to take my shot. It is just like in real golf, use your own skills, ability and memory to play. If you need a journal to play a computer game, then all I can say is, you may have some serious issues, that need dealt with right away. If I am in an AS game on here, and it has a 90 second timer, if you take more than 30-45 seconds to shoot, that is a major annoyance. Do you take a minute and a half to swing in real golf? If you do, please don't invite me to play. I am renniw52, and I have approved this message.
Every single Pro Golfer has a chart usually that the caddie carries that tells him their exact yardage that he/she hits the clubs they use. Also, they have charts in their pockets of distances of bunkers etc etc on each hole. So yes Pro's also use these things in real life. They dont use a tape measurer on the greens, but they can read greens better than we can on WGT because the grids are wrong 1/3 of the time anyways.
Edit: Thanks Run for putting something like this up, it certainly helped me when I first started playing and I created a hybrid to your setup and changed the formula a bit for my own liking. I still cant putt, but this will cut down on 3 putts for 95% of newbies that use it untill they understand the greens a bit better.
