How this works
A stop is detected when you stay inside ~6 m for long enough — 20 s for a landing,
45 s at a known tee or basket. Walking between stops never records anything.
Fixed points accumulate. A tee measured across 5 visits is far better
than any single fix, because it is genuinely the same coordinate each time. A landing
can't be — it happens once — so it stays lower-confidence. That gap is exactly why
surveying is worth it.
Ambiguous stops get flagged, not dropped — too short, phone moved,
weak fix, or near-but-not-on a known point. Everything else records silently.
