Adalanar: Would be great if you could spent some more words on it as I do not get what you tried to explain
Understandable, Adalanar, I'm not sure I'm explaining myself correctly.
Notice the line that runs in front of the cup and the one that runs away from it. Now, draw a line from where you are standing to the line that runs in front but use the shortest line possible. In effect, this line would be parallel to the one that runs away from the cup. The example above shows the before and after.
This is not your aim, it's that starting point for aiming. Note how fast the dots are crossing this line. This is what you need to adjust for because if you hit that putt as it is aimed (the parallel line) you will miss on the low side of the cup. So, if you like aiming by missing you would need to figure out how much to miss by based on the speed of the dots. If you are a dinger then that speed will tell you how much more you have to aim by.
This isn't as much about actually aiming as it is giving you a common starting point for aiming your putt. It doesn't fit all scenarios either. There was a post a long time ago about "putting the grid." I never really understood what that meant but the way the greens are mapped starts with a flat grid. Start your aim the same way and adjust accordingly. Eventually it will become second nature to set that line and then look at the break.
Pay attention to the start of the putt and the end of the putt. Starting off on the wrong line is easy to do if you don't pay attention to the first few feet and how many times have you seen the putt turn away from the cup in the last 2-3 feet?
