Farnsworth Diagrams

Explanation: In putting, the actual hole is rarely ever the target! Using an x/y coordinate system, the idea is to slide the actual hole on the axis to identify and putt at a projected target hole. How much you slide the projected target hole up/down/left/right on either axis is dependent upon how the green is sloped, e.g., uphill/downhill/left-to-right/right-to-left.

Example A
Uphill Left-to-Right Putt
Example B
Downhill Left-to-Right Putt
