Launch Monitor Import
PinFlag turns launch monitor sessions into per-club dispersion truth: imported, fit robustly with outliers flagged, and stamped as measured data — the top-priority source behind your on-course numbers. Sources are never blended, and every number says where it came from.

Launch monitor sessions become durable, per-club dispersion truth. Each import is fit robustly — cold-start shrinkage, outliers flagged rather than silently deleted — and stamped as measured launch-monitor data, the top-priority dispersion source the strategy engine uses. Sources are never blended: a number comes from your launch monitor, your tracked rounds, or a model, and it says which.
Why it matters
- Your real carry numbers and spread live in the launch monitor; decisions happen on the course. This is the bridge.
- Averages hide the pattern — a robust fit of the whole session doesn’t.
- Provenance matters: measured data should outrank a model, and it should say so.
How it works
- 1
Export from your monitor
Trackman, Garmin, or Rapsodo files — or any monitor via a mapped CSV with explicit units.
- 2
Import a session
Sessions keep device, ball, and environment metadata, up to 5,000 shots.
- 3
Get honest fits
Each club’s dispersion is fit with cold-start shrinkage; outliers are flagged, never silently deleted.
- 4
Play with it
The fits become Measured dispersion — the source your live strokes-gained numbers prefer above everything else.
Everything Launch Monitor Import does
- Trackman, Garmin, and Rapsodo file support, plus mapped generic CSV
- Yards/meters and mph/kph handled explicitly at import
- Robust per-club dispersion fit with 3σ outlier flagging — flagged, never deleted
- Durable sessions with device, ball, and environment metadata
- Measured provenance: launch-monitor data outranks on-course and model sources
- Never blended: exactly one dispersion source behind any number
A worked example — real numbers
What tighter dispersion is worth on the green
Proximity is where dispersion cashes out. PinFlag’s putting baselines price the difference between the putts a wide pattern leaves and the putts a tight one leaves.
25 ft left
- Expected putts
- 1.931
15 ft left
- Expected putts
- 1.780
8 ft left
- Expected putts
- 1.500
0.431 strokes better than 25 ft — per approach.
Moving your typical leave from 25 feet to 8 feet is worth 0.431 strokes every time it happens. Knowing your real pattern is how you find aims that produce it.

Who it’s for
Launch monitor owners — simulator players, range-session regulars, fitters’ customers — who want their measured game to be the one the strategy numbers use.
What’s different
- Never blended: launch monitor, on-course, or model — exactly one source behind any number, disclosed.
- A sample-size floor (10 shots per club) before a source is trusted at all.
- Outliers are flagged for you to judge, not deleted to flatter the fit.
- Import is architecturally walled off from the scoring engine.
Frequently asked questions
- Which launch monitors does PinFlag support?
- Trackman, Garmin, and Rapsodo session files are supported directly, and any monitor works through a column-mapped CSV import with explicit unit handling.
- Does PinFlag mix launch monitor data with course data?
- Never. Dispersion comes from exactly one source at a time — launch monitor, on-course, or model — with launch monitor data ranked first. Blending is structurally impossible and tested.
- What happens to outliers in a session?
- They are flagged at three standard deviations and kept visible. You decide what a topped 5-iron means; the fit doesn’t hide it.
- Are meters and km/h handled?
- Yes — distance and speed units are declared at import (yards/meters, mph/kph) so a European export can’t silently corrupt your numbers.
- How many shots does a session support?
- Up to 5,000 shots per imported session, with device, ball, and environment metadata kept alongside.
