Confirm the roles
Before entering a score, identify which side made trump and whether an agreed special condition applied. Then use the selected scoring reference to settle the result together.
Read both changes aloud
Say the team names and net score changes, including zero if one side does not score. The scorebook adds the numbers entered; it does not identify makers or decide whether a hand was euchred.
Correct transparently
If the latest entry is wrong, undo it and enter the corrected pair. For an older mistake, export the original record before rebuilding the session. A short hand note can explain an unusual agreed result.
Keep a separate copy
Export CSV before switching devices or clearing site data. Local browser storage is convenient, but it is not a shared online backup.
