Jim, on second thought, your question is legitimate and crucial, and demands a renewed effort on my part, though I did state that the bigger the number, the bigger the break. Indeed, "moderate" is a relative and abstract notion, and based on the idea of a stopwatch, it should be clarified. First, look at the pace of passing seconds on a watch (you can use http://www.online-stopwatch.com) to internalize it, and later apply it to the gauging process. Then you take as a point of reference a grid line where the balls indicating break travel approximately at a rate of 10 seconds. That will be a moderate break, represented by the number 1. Slower may be 1/2, faster may be 1,5, 2, 2.5, 3, etc. Again practice and experience are essential, and you will learn to make subtle adjustments depending on the speed of the greens. Mind you, all the greens on wgt are often tough to read, especially when the front and reverse views are oddly different, or even contradictory (grrrrrrr). I tend to rely predominantly on the front view, while taking the reverse view into consideration, and as a rule, when I miss the hole, it is by a maddening small fraction, due to a slight miss-gauge or miss-hit.
Incidentally, I must thank all the bright players who have contributed to this thread, and helped me improve my putting formula. Weida is one of them, and now you, Jim. Again, thank you.
