What it does

• Session dashboard — overview of dispersion, carry distribution, ball speed trend, and smash/spin scatter for any club or the full session
• All shots table — filterable, sortable shot log with outlier detection and poor-contact flagging
• Shot detail — per-shot stats (distance, speed, launch, spin, club data) with face-to-path diagram, loft diagram, and impact location overlay
• Bag gapping — distance ladder across your bag: progress bars, sortable stats table, and a horizontal carry ladder with ±1 std dev capsules showing consistency per club; overlaid on a top-down fairway photo with yardage markers and per-shot scatter
• Session compare — load multiple CSVs and compare them side-by-side: overview metrics table, per-club line chart (carry, ball speed, spin, smash, offline) with session dates on the X axis, and a delta table showing signed changes between two sessions
• Club ideals — set ideal ranges per club; stats highlight green/amber/red against your benchmarks
• Dark mode — full light/dark theme
