PinFlag vs. Shot Pattern: Honesty Grammar & Coach Platform
Shot Pattern and PinFlag both start from an idea Mark Broadie helped popularize — that where your shots actually land matters more than a rule of thumb. PinFlag’s shipped difference is a strict honesty grammar, dispersion sources that are never blended, a frozen engine, and a live coach platform.
PinFlag is best for
Golfers and coaches who want dispersion-based numbers with a disclosed measurement basis — Measured or Estimated, never averaged across sources — computed by an engine that’s frozen and hash-verified, plus a roster-wide coach platform that’s live today.
Shot Pattern is best for
Golfers who want a dedicated, standalone tool focused specifically on visualizing where their shots land, independent of any coaching or roster features.
| What to check for | PinFlag | Why it matters |
|---|---|---|
| Measurement basis disclosed | Every reading labeled Measured, Estimated, or Pending — never a confident-looking average | A dispersion number is only as trustworthy as what it’s actually built from |
| Sources blended or kept separate | Exactly one dispersion source at a time — launch monitor, on-course, or model — never blended | Blending sources can hide which one is actually doing the work |
| Underlying engine | Built on Mark Broadie’s published strokes-gained baselines, frozen and hash-verified | The math shouldn’t quietly change between one session and the next |
| Built for a coach and a roster | Yes — command center, per-player review, lessons, assignments, reports | A tool for one golfer is a different job than developing a team |
What’s the honest overlap between PinFlag and Shot Pattern?
Both tools start from the same premise strokes gained made mainstream — that a golfer’s real shot dispersion, not a hopeful average, should drive the number. Where they differ is what’s built around that idea.
Shot Pattern and PinFlag both build on an idea Mark Broadie’s work helped bring into the mainstream: that where a golfer’s shots actually land, not a generic average, should decide what a target is really worth. Shot Pattern’s own site treats shot-dispersion analysis as its core focus. PinFlag starts from the same premise but builds a specific, narrower set of commitments around it: a strict honesty grammar for every number, dispersion sources that are never blended together, a frozen and hash-verified scoring engine, and a live platform for coaches managing a roster.
Availability
PinFlag’s honesty grammar, dispersion handling, and frozen engine ship with its iOS app, currently in pre-release. PinFlag’s coach platform is live today on the web.
What should you look for in any shot-dispersion tool?
Ask whether a number is measured or modeled, whether sources get blended, and whether the underlying math is fixed or shifting — the answers matter more than the interface.
- Measurement basis — does the tool disclose when a number is Measured from real data versus Estimated or modeled?
- Source blending — is your dispersion built from exactly one real source, such as a launch monitor or tracked rounds, or averaged across sources without saying so?
- Engine stability — is the underlying scoring method fixed and verifiable, or does it change quietly over time?
- Who it’s built for — one golfer’s numbers, or a coach’s whole roster?
PinFlag’s answers: dispersion comes from your own launch-monitor sessions or tracked rounds and is fit per club, never averaged with another source; every strokes-gained reading is labeled Measured, Estimated, or Pending rather than shown as one confident number; the scoring engine is built on Mark Broadie’s published strokes-gained baselines, frozen, and hash-verified in CI; and the coach platform managing all of that for a roster is live today.
Which should a coach choose?
A standalone dispersion tool doesn’t give a coach a roster view. PinFlag’s command center does.
A tool built specifically around one golfer’s shot dispersion is solving a different problem than developing a team. PinFlag’s coach platform puts every player’s strokes gained in one command center, with lesson logging, assignable practice tied to a measured leak, and reports built for parents and college coaches — live on the web today, for one coach plus up to 10 linked students.
