25 foot scale is easy to read if you watch the animation of your swing. As you begin to set your power and start your backswing, the first change in graphics(or the position of the club on your screen) will be 8.3 feet. The second "position" you will se as you continue your backswing will be 16.6 feet. And if you can eyeball half way, that gives you 3 points of scale to judge the distance... 1/3, 1/2, & 2/3..
