Thought I'd share this.
A method of comparison.
Both DEA and gameclient can be logged into at the same time.
In DEA I choose 1024 x 768. In gameclient, I stretch the window to 1024 wide. (I have a program that makes this easy to do, but anyone can get close by just carefully dragging the windows above and below each other. A pixel or two won't matter.) The aspect ratio of the two is slightly different, so the heights will be off by a bit, but getting the width the same or close is what's important.
I open up both and head for the medium putting green. I choose my spot by clicking on the top of the flagstick. This gets me to exactly (or real close) to the same position in both windows. There's some window overlap (monitor is 1920 x 1080) but the important middle part of both is visible.
Compare the dot movement, grid by grid.
When WGT gets them at least close to each other, game on.
I had a screenshot of the method above, but in this small format, it was pretty useless.
