Indoor vs Outdoor
Why Your Bay Numbers and Your Course Numbers Disagree
Six separate mechanisms sit between an indoor carry figure and what your ball does on a Saturday in April. Only two of them are the machine's fault.
Lab Notebook
Working notes, mostly about the gap between a screen and a golf course
These are not articles written to rank for anything. They are the explanations we found ourselves repeating in the bay, written down once so we could point at them instead. Several exist because we got something wrong and had to work out why.
Capture Hardware
Doppler and Optical, Side by Side in One Bay
What each system measures directly, what it works out by inference, and the specific places where the inference stops being trustworthy indoors.
Normalization
Air Density, Altitude and the Carry Model We Apply
The arithmetic behind the adjusted column on your condition sheet, written out so you can check it rather than take our word for it.
Documentation
The Condition Sheet: Recording What Surrounded Each Number
Why we started printing the room alongside the results, what goes on the page, and the three arguments it has already settled.
Data Handling
Which Strikes We Discard, and Why We Tell You
A discard rule you cannot see is a discard rule you cannot check. Ours is stated before your first swing and the count is printed afterwards.
Normalization
Reference Ball Choice and the Spin Numbers It Moves
A tired range ball can under-read spin by a margin large enough to change a shaft recommendation. Here is how we control for it.
Why we write these
Because "trust us, we measured it" is not good enough
Everything on this site rests on a claim that our measurement practice is more careful than the norm. That claim is worthless unless the practice is written down somewhere a sceptical reader can pick it apart.
