One reading tells you nothing. Ten, measured the same way, tells you plenty.
A tee number and a game number are not the same number, and two devices rarely agree. This log groups every session by player, setup and device, so progress is only ever measured against readings taken the same way — which is the only way a trend means anything.
- Sessions grouped by player + setup + device, so you never compare a tee number to a game number
- Personal best and change-vs-last-session computed inside each group
- Progression chart for any single group
- Excel + Google Sheets workbook, plus a printable session log
