The short-game guru, Dave Pelz, concluded that a golfer should, on longer putts, plan to have enough pace on their ball, that if the putt was going to miss, it would travel up to 17 inches past the hole. At that pace:
• the ball is getting up to the hole,
• isn’t as vulnerable to slope in its final travel to the hole making the line easier to read,
• yet is slow enough to drop in from a high-side lip,
• But if it does miss, then a 17-inch putt is no challenge coming back.
Find some time on the practice green to see if the 17-inch rule is a magic number for you. And while you’re at it, watch and learn what the ball is doing as it gets to a hole with some side-slope.
