Strokes Gained is the most revolutionary metric in golf analytics since the invention of par. Developed by Columbia Business School professor Mark Broadie and published in his 2014 book 'Every Shot Counts', Strokes Gained quantifies exactly how much better or worse a shot is compared to what an average PGA Tour player would score from that same position. Before Strokes Gained, golf statistics were siloed and misleading — a player could lead the tour in greens in regulation while actually being a poor iron player saved by elite putting. Rory McIlroy's 2023 season demonstrated Strokes Gained's power: his Strokes Gained: Off-the-Tee was +1.2 per round, meaning his drives alone saved him over a stroke per round compared to the average tour professional. The metric uses a massive database (ShotLink on the PGA Tour covers every shot from millions of rounds) to establish a benchmark: from any position on the course (distance, lie, conditions), what does an average PGA Tour player score from here to hole out? Your actual score minus that benchmark, subtracted and flipped in sign, is your Strokes Gained for that shot. Strokes Gained can be decomposed into four categories: Off-the-Tee (driving), Approach the Green (iron play), Around the Green (chipping/pitching), and Putting. This decomposition allows coaches and players to identify exactly where strokes are being gained or lost. The metric has limitations: it requires large shot databases for accurate benchmarks, is less reliable at amateur level due to smaller sample sizes, and doesn't capture course management decisions directly. Nevertheless, Strokes Gained has transformed how the PGA Tour evaluates talent and how serious golfers diagnose their games.
Strokes Gained (single shot) = Baseline Score from Start Position - Baseline Score from End Position - 1. Total Strokes Gained = Sum of all individual shot Strokes Gained across a round. Baseline scores come from empirical PGA Tour ShotLink data. Example: Rory McIlroy drives to 150 yards on the fairway. Baseline from tee (par 4) = 4.0 strokes to hole out. Baseline from 150 yards fairway = 3.0 strokes to hole out. SG for drive = 4.0 - 3.0 - 1 = +0.0 (average drive). If he reached 100 yards: SG = 4.0 - 2.7 - 1 = +0.3 (gained 0.3 strokes on field).
- 1Record the starting position of each shot: distance to hole, lie type (fairway, rough, bunker, green), and whether it is a tee shot.
- 2Look up the baseline expected strokes to hole out from that starting position using the ShotLink benchmark database for the appropriate golfer category (PGA Tour, amateur, etc.).
- 3Record the ending position after the shot is played: new distance to hole and new lie category.
- 4Look up the baseline expected strokes from the ending position.
- 5Calculate Strokes Gained for that shot: Baseline Start - Baseline End - 1 (the 1 accounts for the shot itself).
- 6Sum all individual shot Strokes Gained values across the round for a total, or group by category (off-tee, approach, around green, putting) for decomposed analysis.
- 7Compare the player's total or category Strokes Gained against tour average (0.0) or against specific competitors.
McIlroy's elite iron play to 8 feet gained half a stroke on the field compared to an average PGA Tour approach from the same distance.
A three-putt from 40 feet loses exactly one stroke to the field since the benchmark says an average tour player needs 2 putts from that distance.
Even a well-executed lay-up from deep rough can show a slight negative Strokes Gained if the average tour player would gain more by attempting the green.
An exceptional 350-yard drive to the fairway on a par 5 gains a full stroke on the field, illustrating why elite driving distance is so valuable.
Electrical engineers in power distribution companies use Golf Strokes Gained to size conductors, calculate voltage drop across long cable runs, and verify that circuit breaker ratings provide adequate protection against fault currents in residential, commercial, and industrial installations.
Electronics design engineers apply Golf Strokes Gained during printed circuit board layout to determine trace widths for required current capacity, calculate impedance matching for high-speed signal traces, and verify thermal dissipation in surface-mount components under worst-case operating conditions.
Maintenance technicians in manufacturing plants use Golf Strokes Gained to troubleshoot motor control circuits, verify transformer tap settings, and calculate expected current draws when commissioning variable frequency drives and programmable logic controller systems.
Renewable energy system designers rely on Golf Strokes Gained to size solar panel arrays, calculate battery bank capacity for off-grid installations, and determine inverter ratings that match the expected peak and continuous load demands of residential and commercial photovoltaic systems.

In practice, this edge case requires careful consideration because standard assumptions may not hold. When encountering this scenario in golf strokes gained calculations, practitioners should verify boundary conditions, check for division-by-zero risks, and consider whether the model's assumptions remain valid under these extreme conditions.

What is a good Strokes Gained per round on the PGA Tour?
Golf Strokes Gained is a specialized calculation tool designed to help users compute and analyze key metrics in the engineering and electrical domain. It takes specific numeric inputs — typically drawn from real-world data such as measurements, rates, or quantities — and applies a validated mathematical formula to produce actionable results. The tool is valuable because it eliminates manual calculation errors, provides instant feedback when exploring different scenarios, and serves as both a decision-support instrument for professionals and a learning aid for students studying the underlying principles.
What is Strokes Gained: Putting vs. regular putting stats?
Traditional putting stats like putts per round penalize players who miss greens (fewer putts if you chip in) and reward poor approach players (more putts after bad approaches). Strokes Gained: Putting isolates only what happens on the green, correctly crediting one-putts after close approaches and not penalizing for two-putting from 60 feet.
Can amateur golfers use Strokes Gained?
In the context of Golf Strokes Gained, this depends on the specific inputs, assumptions, and goals of the user. The underlying formula provides a deterministic relationship between inputs and output, but real-world application requires interpreting the result within the broader context of engineering and electrical practice. Professionals typically cross-reference calculator output with industry benchmarks, historical data, and regulatory requirements. For the most reliable results, ensure inputs are sourced from verified data, understand which assumptions the formula makes, and consider running multiple scenarios to bracket the range of likely outcomes.

プロのヒント
Focus your practice time on the Strokes Gained category where your number is most negative relative to your handicap peers. Research shows improving weak areas delivers more total improvement than sharpening already-elite skills. Scottie Scheffler improved from -0.2 to +0.8 SG: Putting from 2021 to 2023, which drove his ascent to world No. 1.
