Ill try to explain a little bit.
May be best to look at the video while reading the following.
go to putt 2 on this video & start watching from there.
Each square in front of the putt has a line
Each line has a moving dot
Each dot has a speed
Each dot on each line can be the same speed as the one in front or behind or can be different speeds
In regards to dot speeds i would rate 0 been not moving & 10 been Oak 1st hole. Beth 2nd & 3rd hole back pins been 2.5 - 3 in regards to speed of the DOT or DOTS on the line are moving.
The thing to work & practice on is how much to move your line compared to how fast those dots are moving & if they are all moving the same speed on every line in front of you & you know how much to move your putter line/blue marker for each of those DOTS just a matter of counting how many lines there are & hitting the ball with aggression as you said in a past post it looked like I was counting how i was moving my putting line & also the same for allowing for wind with iron shots.
Hard thing to teach & explain
