The Monte thesis · Post-round analysis · Updated Aug 2026
Decision or execution? Autopsy your strokes.
The scorecard is a coroner that only records that somebody died. A double bogey doesn't say whether the plan was wrong, the swing was wrong, or nothing was wrong at all. Those are three different deaths — with three different, differently-priced fixes.
The blind spot
The card records outcomes. Golfers need causes.
Here is the most common conversation in golf, held silently, in a cart, with oneself: I made 7 on a par 5 I can reach. I am bad at golf. I should practice more. Practice what, exactly? The 7 doesn't say. It never says.
Every number on a scorecard is the product of three ingredients: the quality of the decision, the quality of the execution, and luck — the ordinary variance of a human swinging a stick. The card multiplies them together and reports one integer. Working backwards from that integer to the ingredient that failed is the single most valuable analytical act in golf, and almost nobody performs it. Instead we do what poker players call resulting — judging the decision by the outcome. Shot came off: great call. Shot drowned: stupid call. Annie Duke wrote a whole book about why this instinct quietly ruins decision-makers, and golfers might be its purest victims.
A good decision that fails is still a good decision. A bad decision that succeeds is still a lesson you'll pay for later — with interest.
The anti-resulting principle, applied to golf
The taxonomy
One double. Three autopsies.
Take the watery 6 from our par-5 walkthrough: 230 to carry, 3-wood at the green, splash, drop, wedge, two putts. Same number on the card — three completely different stories underneath, depending on what your dispersion pattern says about that 3-wood.
Decision error
Your 3-wood carries 224 on average and the water demands 218 — a third of your pattern was wet before you swung. The lay-up priced out half a stroke better. The swing you made was fine; it landed inside your normal cloud. The plan put the cloud in the wrong place.
Fix: free — better planning. No range balls required.
Execution error
The numbers actually favored going for it — say the water only needed 205 and your whole pattern covers that. But you hit it off the toe, a shot that lands far outside your normal ellipse. Right plan, wrong strike. The decision deserves to be repeated; the swing deserves the range.
Fix: expensive — practice, targeted at that club and that miss.
No error at all
The go decision priced best and the strike was normal — it just came down in the wet tail of a good bet. A 15% drowning risk drowns 15% of the time; that's not a mistake, that's arithmetic showing up. Changing anything after this outcome is how good strategies get abandoned.
Fix: none — keep making that bet, forever.
Notice what just happened: identical scorecard, and the correct responses range from “change your planning” to “book a lesson” to “change absolutely nothing.” Resulting collapses all three into I'm bad at golf — which fixes none of them and usually makes the next decision worse, because scar tissue is a terrible caddie.
The method
Two questions, asked in order.
You can run this autopsy with a pencil. After the round, take each blow-up hole and ask exactly two questions — in this order, because the first one is about the plan and the plan came first:
Question one — the decision
Knowing my honest pattern, was this the cheapest plan available? Not “could it work” — did it price best? If your ellipse hung over water or short-side sand more than the alternative did, the stroke died in the planning, whatever the swing looked like.
Question two — the execution
Did the shot land inside my normal cloud? Inside: the swing did its job — see question one, or accept variance. Well outside — the shank, the top, the double-cross: that's execution, and it earns a spot on the practice list with its club and its direction attached.
Both questions lean on one prerequisite: knowing what your normal actually is. That's why the honest ellipse from our dispersion guide and the real carries from the club calculator come first — without them, every autopsy verdict defaults to “bad swing,” because the plan was never written down and normal was never defined.
The timing rule
Decisions are graded at the moment they're made — never after the ball lands. The pre-shot test: could you defend this club and target to a good caddie, out loud, using your honest pattern? If yes, the decision is sound no matter what happens next; the post-round autopsy only files the outcome under the right cause. Grading plans by results is how one lucky hero shot buys ten expensive imitations.
The economics
Fix the free leak first.
The two error types have wildly different repair costs. Execution improvements are bought with months of range time, coaching, and a body that cooperates. Decision improvements are bought with a pencil: they cost nothing, they apply on the very next round, and they don't decay with age or a stiff back. For most amateurs the decision leak is worth strokes per round — which makes it the highest-return purchase in golf at a price of zero. (That asymmetry is the entire argument of our course-management 80/20 guide.)
There's a second asymmetry, crueler: unexamined decision errors masquerade as execution errors. The golfer who always plans on career carries lands short all day, concludes the swing is broken, and buys lessons for a planning problem. The range can't fix what the plan keeps breaking. Autopsy first; spend second.
Where Monte fits
The autopsy, automated.
This page is the founding idea of Monte. During the round, the engine prices every plan against your real dispersion — 4,096 outcomes per option — so decisions are graded before the outcome, the only honest time to grade them. After the round it runs the two questions on every stroke you lost: this one died in the plan, this one in the strike, this one was just the tail of a good bet. Your practice list gets the execution errors, your next plan absorbs the decision errors, and the good bets that went bad get what they deserve: repetition.
