Circle the Pin
Why this drill
Chipping's only honest statistic is how often you leave yourself a tap-in. A flagstick laid flat draws the circle; ten chips against it give you a conversion number to beat — and tap-in range is where up-and-downs are actually decided.
Setup
Lay a flagstick (or an alignment stick) flat with its base at the hole — the stick's length is your circle's radius. Ten balls from a spot just off the green, one wedge.
The drill
Ten chips from the same start, each to a finish inside stick-length of the hole. Score out of ten, then move to a second station — different length, different lie — and score again. Six of ten from friendly lies is solid; four of ten short-sided is better than most single-digits manage. The circle converts "pretty close" into yes or no, and the number is what improves, session over session, when the towel drill's landing-spot skill starts paying off.
