how can i get better at judging the line of a putt
To improve judging the line of a putt, focus on matching pace control to the required line, using physical feedback from your feet to sense slope, and ensuring your putter face is aimed precisely at your intended start line.
Key Insights
Pace and line are interdependent; you must commit to a specific entry speed before you can accurately determine the correct aim point for a putt (src_1).
Use your feet to sense the percentage of slope by feeling weight distribution toward the 'low' side, which can then be used to determine the starting line (src_3).
Use alignment aids during practice to verify that your putter face is actually pointing at your intended start line, as your perception of 'square' can be inaccurate on breaking putts (src_1).
