Working Notes
Six entries about measurement rather than equipment, because most bad fitting decisions trace back to reading a number the wrong way rather than to choosing the wrong club.
Indoor Bay or Outdoor Grass: Which Session Is Telling the Truth?
The bay gives you control and the range gives you reality, and neither one is sufficient alone. What each environment is genuinely good at, and where each one quietly misleads you.
Read it →Radar and Camera Launch Monitors Are Not Measuring the Same Thing
One tracks the ball in flight and works backward to the club. The other photographs impact and works forward to the flight. Which numbers each one actually measures versus calculates.
Read it →Making Two Sessions Comparable
Your March numbers and your August numbers are not the same currency. How we normalize for conditions, ball, and equipment before drawing any conclusion across dates.
Read it →Heat, Humidity, and Why Coastal Carry Numbers Confuse People
Humid air is less dense than dry air, which is the opposite of what almost everyone assumes. What that actually does to your carry on a Savannah afternoon, and how much of it matters.
Read it →The Ball You Test With Changes the Answer
Range balls spin less and fly shorter, and the gap is not a flat percentage across the bag. Why that can hand you the wrong wedge bounce and the wrong driver loft.
Read it →How Many Swings Is Enough?
Five shots is noise, fifty is fatigue. Where the useful middle sits, why we trim the extremes, and how to tell a real difference from a run of good luck.
Read it →Measurement Beats Equipment
We could write about the newest driver head every quarter, and plenty of people do it better than we would. The questions that actually come up in our bays are duller and more useful: why do these two numbers disagree, why did my carry change since spring, how many balls do I need to hit before this comparison means anything.
Every entry here came out of a conversation with a golfer standing in a bay looking confused at a screen.

If there is a measurement question you have never had answered properly, send it over. We will either answer it by email or, if it is a good one, test it on a closed afternoon and write it up.
