One thing I got from GOLD's method is that in order to make sense of the dots, you need to have a pretty good feel for how long the putt will take to get to the hole + a foot or so. Find an unlimited tourney at Kia. Keep restarting until you get that magic 1-3 wind. #1 green isn't perfectly flat, but it's pretty good. Get on the green and putt back and forth from various distances. Helps if you have a stopwatch. There are several free ones available.
Now armed with that knowledge, time the dot movement for the appropriate distance for your putt. Move the aimer accordingly. Ding the putt. :^)
Multiple speeds to the dots? I just time the average speed one. Usually, if you have that many to choose from, two putting is a good outcome, with the odd one dropping.
Multiple break? Contrary to real golf, in WGT land the first arc is just as big a deal as the last. Read it as two (more) putts. As before, you're just trying to have that tap in for a two putt.
Good Luck.
