I have always had trouble figuring this out and just guess for the most part.
also do you people move the cursor when putting or try and time the cursor to match the break?
thanks :)
Like some previous posters, I've found that it's more of an "educated guess" that is used when judging the breaks, the necessary aim-adjustments, and the associated putt-strength.
Beyond this, however, I think that the single, most important element involved with putting in this game (besides practice, of course), is the ability to discern when the need to "putt through the break" presents itself.
After seeing ALOT of my medium-length putts come-up short, with a "curly-Q" - leaving the ball 6" in front of the hole, I decided to modify my thinking a bit, and add more power to the putts. On the "practice greens", I did this in increments where I added more power, while decreasing the distance of the aimer from the cup - all dependent upon the various speeds of the "grid-balls" and in-line slopes. Relying on this newfound knowledge, as well as adding in a bit of faith, enabled alot more of my putts to drop. (Especially the 3-4ft ones like you'll find at BPB #15's original pin location at the front of the green.)
Judging the breaks is still a "feel thing", but realizing that there are times when you MUST take the chance of "overstroking" one, is an essential part not to be neglected while developing this "feel".
Good Luck. ;^)
