Identify what actually costs strokes
Look beyond the shot you dislike most. Penalties, three-putts, poor wedge distance control, and avoidable decisions often deserve attention before cosmetic swing changes.
Blocked versus random practice
Blocked practice—repeating one shot—can help calibration. Random practice changes club, target, or lie and better tests whether the skill transfers. A sensible session often uses a short blocked phase followed by variable work.
Measure a result
Count fairway corridors hit, putts finishing inside a zone, or chips ending within a useful radius. Record one number and compare it under the same conditions later.
Keep sessions repeatable
Two clear priorities in 45 minutes are more useful than seven rushed categories. End by noting what happened and what the next session should test.
