You can hit a hundred seven-irons on the range, stripe eighty of them, and still lose the club by the third hole. The problem is not talent. It is the structure of the practice.
Block practice — same club, same target, same lie, ball after ball — builds a feel that evaporates the moment the context changes. The course never gives you the same shot twice, so a skill rehearsed in a single context does not transfer to a random one.
The fix is to make practice look more like a round. After a short technical warm-up, switch to random blocks: change club, target, and intention every ball. Play nine imaginary holes on the range. Miss and move on, exactly as you would on the course.
If it feels harder and your range numbers drop, you are probably practicing correctly.
Anchor the block with a measurement so you know it worked. A putting mat with a gate, a rangefinder to hold you to a real target, an alignment station you rebuild every few balls — each gives you a number that tells the truth about transfer, not a feeling that flatters you.
Twenty minutes of structured, random, measured practice beats an hour of comfortable repetition. Log it, watch the on-course number, and adjust the block — not your swing — when it stalls.
