Every coaching insight depends on the underlying course data being right. Here's how we approach it — and why it matters for your stats.
Coverage targeting all 50 states, with thousands of courses verified at launch and the catalog growing every round played.
Our handicap calculations are built to the published World Handicap System specification — Net Double Bogey cap, slope-adjusted differentials, and best 8 of the last 20 rounds.
Multiple independent inputs are cross-checked for each course. No single information source is complete, so we layer them carefully and let coverage compound over time.
Course catalog access is included with your subscription. No "premium catalog" upsell, no separate paywall, no extra fee.
We start with publicly-licensed mapping data that identifies course locations, names, and basic facts — the same kind of foundational data that powers navigation apps. It gives us a verified base of thousands of US courses with accurate GPS coordinates.
We supplement the mapping foundation with cross-referenced GPS coordinates and course-type information — public, municipal, private, semi-private — from independent archives. This fills geographic gaps and adds context.
Address, phone, year built, course architect, hole count — all sourced from publicly-archived course information and verified against multiple references. So we can show a real course detail page, not just a name on a map.
For accurate handicap calculation, every tee needs an official rating and slope. We integrate recognized rating data — separate for men and women, separate for front 9, back 9, and full 18 — built to the World Handicap System specification. Coming with v1.1.
Hole-by-hole par, yardage, and stroke index data is rarely in any single public source. So we built a path: snap a photo of a paper scorecard after your round, our system reads it, and the information is added to the catalog for the next golfer. Coming with v1.1.
Greens in regulation, scoring breakdown, scrambling — every diagnostic stat we show you depends on the underlying course data being right. Wrong par on a hole? GIR number is wrong. Wrong rating? Handicap is wrong. So we invest heavily in data quality because the coaching value of My Golf Insights depends on it.
No catalog has every course. Small munis, brand-new builds, members-only clubs — these take time to verify. When that happens to you, My Golf Insights still lets you play your round. Enter pars manually now; snap a scorecard photo once OCR ships in v1.1. You're never locked out.
Handicap index calculation has a specific shape under the World Handicap System: Net Double Bogey cap, slope-adjusted differentials, best 8 of the last 20. We build to that spec. Once our v1.1 rating integration ships, your handicap index is designed to closely match any WHS-compliant handicap service.
No "premium catalog" upsell. No course-search paywall. Catalog access is included. We invest in data quality steadily as the user base grows — not behind a separate paywall.
