Every tap writes to the phone instantly. The marker decides when to submit — after a hole, at the turn, or at the 19th. Nothing is auto-synced, so nothing gets accidentally overwritten.
The base for each new round is that course's HNA Course Handicap — not the previous round's playing HC. Score over 34 cuts shots; under 24 adds shots. Recalculated this way for every round of a multi-day tournament, with every calculation persisted with full provenance.
