Seventeen Inches Past
Why this drill
A putt dying at the front edge is at the hole's mercy; a putt rolling a bit more than a foot past hits the hole at its widest effective size. Training one dying speed — about seventeen inches past when it misses — makes more mid-range putts fall without adding three-putt risk.
Setup
A hole with six to fifteen feet of run-out behind it. Lay a club or alignment stick across the line seventeen inches behind the hole — a putter grip's length is close enough. Ten balls at eight feet.
The drill
Roll ten putts. A make counts, and so does a miss finishing between the hole and the stick — both mean the speed was right. A putt short of the hole, or one that reaches the stick, is wrong regardless of line. Score speed-right balls out of ten, then repeat from twelve and then fifteen feet. Most players discover they are chronically short; the stick recalibrates what "dying speed" actually looks like within two sessions.
One thought to take with you
See the ball tipping in over the front edge on its last half-turn — then roll it at that picture.
