A manual record
Enter the signed change for each player after your group agrees the result. There is no automatic picker/partner selection, bonus multiplier, penalty or winner decision. A non-zero hand sum is a review prompt, not a computed correction.

If saving fails
A warning identifies the session as temporary. You can keep entering and export a copy, but should not assume the record will survive leaving the page. Administrator login does not back up visitor scorebooks.
