You've seen the guy. Maybe you've been the guy. He buys the jumbo bucket, drags it to a mat, and hits 7-iron after 7-iron at the same flag for forty-five minutes. Some shots are great. He leaves feeling productive. And in three months his handicap hasn't moved an inch.
That's not a character flaw — it's a practice-design flaw. The way most golfers practice is almost perfectly engineered to feel good and change nothing. The fix isn't more balls or more hours. It's intent: knowing what each shot is for, getting honest feedback on it, and making the session hard in the specific way that golf is hard.
Block practice feels great. That's the problem.
Motor-learning researchers draw a line between two ways of practicing. Block practice means repeating the same skill over and over — thirty 7-irons in a row. Random practice means shuffling skills constantly — driver, then wedge, then 5-iron, never the same shot twice, the way an actual round works.
Here's the twist the research keeps confirming: block practice makes you better during the session, and random practice makes you better later, when it counts. This is called the contextual interference effect, and it's one of the most replicated findings in skill acquisition. A 2024 meta-analysis in Scientific Reports found that high-interference (random-style) practice reliably beats blocked practice on retention tests — you keep more of what you learned. A golf-specific study on putting found the same pattern: the random-practice group putted worse during training but better on the retention test, and built a stronger mental representation of the stroke.
Why? When you hit the same shot thirty times, your brain stops solving the problem after shot three. You're running a groove, not learning. When every shot is different, you're forced to re-read the situation, re-select the motion, and re-execute from scratch — exactly what the first tee demands. That extra effort is the learning. It just doesn't feel like it, because random practice looks messier in the moment.
This is the single biggest reason range heroes shoot 95. They've trained a skill golf never asks for: hitting the same shot twice in a row from a perfect lie with no consequences.
Block practice still has a job. When you're making a genuine technique change — new grip, new takeaway, something Pat gave you in a lesson — you need repetitions to build the pattern before you can stress-test it. The rule of thumb: block to build a move, random to own it. Most golfers get the ratio backwards and spend 90% of their time blocking a swing they already have.
No feedback, no learning
The second ingredient is a real feedback loop. Learning requires three things on every rep: an intention (what you were trying to do), a result (what actually happened), and a comparison between the two. Kill any leg of that and you're not practicing — you're exercising.
Outdoor ranges quietly kill the middle leg. Range balls fly short and spin weird, distances are guesses, and "that felt flush" is doing all the evaluation work. Your feel is a famously unreliable witness — the swing that feels terrible often produces the better number.
A launch monitor closes the loop with numbers that don't flatter you: carry distance, start line, curve, spin, face angle. When you call a shot — "155 carry, small draw" — and the screen tells you it carried 149 and cut, you have real information. Do that a hundred times a session and you're accumulating exactly the calibration knowledge that separates players who know their game from players who hope.
One important caveat, straight from the research: don't marinate in the data after every single swing. Motor-learning scientists call this the guidance hypothesis — when learners get detailed feedback on every trial, they start leaning on the screen instead of their own senses, and performance collapses when the feedback disappears (say, on an actual golf course). The practical move: call your shot, hit it, guess your numbers before you look, then check. You're training your internal feedback system to agree with the radar, which is the skill you actually take to the course.
Why a sim bay beats a bucket
Put those two ideas together and you can see why an hour in a launch-monitor bay is worth several buckets. In a bay you get honest ball data on every shot, real distances with a real ball instead of range-ball fiction, and — this is the underrated part — an effortless way to make practice random. Playing nine holes of GSPro is random practice: every shot is a different club, a different target, a different consequence, with a score attached. The simulator does the interference for you.
It also gives you pressure, which the range can't. A 6-footer to save par on a sim round is a fundamentally different rep than the fourteenth putt in a row on a practice green. Golf.com's simulator-practice guidance lands on the same principles: every shot needs a specific target, track the data, and build in challenge instead of mechanical repetition.
None of this means grinding a bucket is worthless — it means it's a tool for one narrow job (building a new move), and most golfers use it for everything.
The 30-minute session
Here's a plan that fits a half-hour bay slot and respects everything above:
- Minutes 0–5: Wake up. A few wedges at half speed, then two or three mid-irons. No judging. You're finding the ground, not fixing your swing.
- Minutes 5–15: Block work — one thing. Pick your single current priority (start line with the 7-iron, low-point with wedges, whatever Pat gave you). Ten to fifteen focused reps. Guess your numbers before you peek at the screen.
- Minutes 15–28: Random challenge. Play a game with consequences. Nine "holes" where you call a different club and target every shot and score yourself pass/fail, or three holes of GSPro played dead seriously. Never the same club twice in a row.
- Minutes 28–30: Write down one sentence. What did you learn? What's the priority next time? A session that ends in a sentence beats one that ends in a shrug.
The 60-minute session
With a full hour you can run the real structure:
- 0–8: Warm-up ladder. Wedge, 9-iron, 7-iron, hybrid, driver — two or three balls each, building speed gradually.
- 8–23: Block work. Same as above: one priority, focused reps, guess-then-check on the monitor. If you're not changing anything right now, use this window for calibration instead — hit five balls with each scoring club and write down your actual average carry, not your best one. (That number will humble you and then save you strokes.)
- 23–33: Skill test. Something measurable you repeat every session so you can see progress across weeks. Example: nine wedge shots to three different distances, one point per ball inside a set window. Same test, every visit. This is your scoreboard.
- 33–55: Play golf. Six to nine holes of GSPro at full attention — pick targets, commit, accept results. This is your random practice and your pressure training in one.
- 55–60: Debrief. Note your skill-test score, your one lesson, and next session's priority.
Make it a loop, not a lifestyle overhaul
Notice what's not in these plans: raking another ball over before the last one lands, chasing a swing thought for forty minutes, or ending because the bucket is empty. Intent isn't intensity. It's just three questions, asked relentlessly — what is this shot for, what actually happened, and what does that tell me?
Run that loop for a month of bay sessions and track one number: your repeating skill test. If it's climbing, your practice is working. If it's flat, change the practice — not the effort. The bucket-beater works plenty hard. He just never checks whether the work is landing. You will.
