Patent ID: 7887427

Claim:
A method for calculated putting, comprising the steps of: establishing a first point across a pre-selected grade on a green surface that is a preselected number of pacing steps from a golf ball; marking said first point; putting said golf ball to said first point white noting a backstroke length effective for said putt; initializing a pre-programmed computing means by inputting said backstroke length effective for said putt; inputting into said computing means, for each segment of a planned putt on a specific green, the length of said each segment; outputting for said planned putt from output means of said computing means the necessary length of backstroke to cause a putted ball to travel across said specific green close to a cup thereof, said necessary backstroke length which is dependent upon and varies responsive to said backstroke length effective to putt said golf ball to said first point input during said initializing step; and putting with a backstroke modified in accord with said necessary length of backstroke; further comprising the step of storing said preselected number of pacing steps as a number in said pre-programmed computing means prior to said inputting step; and wherein the steps of storing said preselected number of pacing steps, establishing a first point, marking said first point, putting said golf ball, and initializing a pre-programmed computing means comprise initialization of said pre-programmed computing means that indirectly determines real-time green resistance.
