MY SYSTEM \u00b7 STEP 01<\/span><\/p>\n<\/div>

How to measure<\/span><\/h1>\n<\/div>

Three tools, one principle: every swing is a data point. In three years, I've documented 4,063 range swings\u2014laying the groundwork for all subsequent analysis.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div>

WHY I MEASURE AT ALL<\/div>\n

\u201eIf you want to train measurably, you have to be able to measure measurably.\u201d<\/p>\n

As a marathon runner (Berlin 1981, 2:26 h) I learned how important consistent documentation is. In golf, the effect is even more pronounced: a single stroke tells you nothing.<\/p>\n

First the 100, 500, 2,000 Repetition<\/strong> creates a pattern. And patterns are the raw material for improvement. I consistently use three tools\u2014one for the range, one for the space, and one for the evaluation.<\/p>\n<\/div><\/div><\/div>

TOOL 1 \u00b7 THE RANGE<\/div>\n

Garmin Approach R10<\/h2>\n<\/div>

My launch monitor since spring 2023. Every shot is captured: carry, total distance, ball speed, club head speed, spin, swing path, launch angle.<\/p>\n

What tour pros paid \u20ac8,000 for a Trackman ten years ago, I can get today for under \u20ac600. The data isn't exactly tour-level \u2014 but it's precise enough to make trends visible over thousands of shots.<\/p>\n

\n
MY SETUP<\/div>\n

R10 on tripod, app on iPad (instead of smartphone - larger screen). Before each shot: correct club selected. After each range session: data exported as CSV to my Excel.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>

TOOL 2 \u00b7 THE SPACE<\/div>\n

Bebrassie GPS Tracking<\/h2>\n<\/div>

The range shows me how I theoretically hit. The course shows me how I do it actually<\/em> Tuesday \u2014 under pressure, in the wind, with the last hole in mind.<\/p>\n

Bebrassie runs on a smartphone in a buggy or on a trolley. Each stroke is recorded by GPS: previous position, subsequent position, chosen club, distance. After the round, I not only have the score, but 54 documented blows<\/strong> (Example Wendlohe Course C, 06\/12\/2026).<\/p>\n

\n
WHY THIS IS IMPORTANT<\/div>\n

Range data and course data often tell different stories. On the range, I hit my PW 90 meters with a standard deviation of 7 meters. On the course, under pressure, it's more like a standard deviation of 12 meters. Only those who measure both can see the difference \u2013 and train both effectively.<\/p>\n<\/div>\n<\/div><\/div><\/div>

\"GPS<\/p>\n<\/div><\/div><\/div><\/div><\/div>

\"Excel<\/p>\n<\/div><\/div><\/div>

TOOL 3 \u00b7 THE DATABASE<\/div>\n

Excel as a Central Data Source<\/h2>\n<\/div>

Data from R10, data from Bebrassie, data from performance tests \u2014 it all ends up in a single Excel file. Grown over three years, today 50 columns and 4,063 rows<\/strong>.<\/p>\n

Why Excel and not a specialized tool? Three reasons: Flexibility<\/strong> (define each column yourself), Property<\/strong> (my data belongs to me, not a cloud provider), AI Compatibility<\/strong> (Claude and ChatGPT understand Excel immediately \u2014 see Step 5<\/a>).<\/p>\n

TOOL 4 \u00b7 THE PROTOCOL<\/div>\n

Performance tests with pencil<\/h2>\n<\/div>

Not everything can be measured with technology. Some things require pen, paper, and discipline. I'm currently running four performance tests in parallel:<\/p>\n
